ItsMyCode: [Solved] AttributeError: ‘str’ object has no attribute ‘get’
The AttributeError: ‘str’ object has no attribute ‘get’ mainly occurs when you try to call the get() method on the string data type. The attribute get() method is present in the dictionary and must be called on the dictionary data type.
In this tutorial, we will look at what exactly is AttributeError: ‘str’ object has no attribute ‘get’ and how to resolve this error with examples.
What is AttributeError: ‘str’ object has no attribute ‘get’?If we call the get() method on the string data type, Python will raise an AttributeError: ‘str’ object has no attribute ‘get’. The error can also happen if you have a method which returns an string instead of a dictionary.
Let us take a simple example to reproduce this error.
# Method return string instead of dict def fetch_data(): output = "Toyota Car" return output data = fetch_data() print(data.get("name"))Output
AttributeError: 'str' object has no attribute 'get'In the above example, we have a method fetch_data() which returns an string instead of a dictionary.
Since we call the get() method on the string type, we get AttributeError.
We can also check if the variable type using the type() method, and using the dir() method, we can also print the list of all the attributes of a given object.
# Method return string instead of dict def fetch_data(): output = "Toyota Car" return output data = fetch_data() print("The type of the object is ", type(data)) print("List of valid attributes in this object is ", dir(data))Output
The type of the object is <class 'str'> List of valid attributes in this object is ['__add__', '__class__', '__contains__', '__delattr__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', '__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'capitalize', 'casefold', 'center', 'count', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'format_map', 'index', 'isalnum', 'isalpha', 'isascii', 'isdecimal', 'isdigit', 'isidentifier', 'islower', 'isnumeric', 'isprintable', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans', 'partition', 'removeprefix', 'removesuffix', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill'] How to fix AttributeError: ‘str’ object has no attribute ‘get’?Let us see how we can resolve the error.
Solution 1 – Call the get() method on valid dictionaryWe can resolve the error by calling the get() method on the valid dictionary object instead of the string type.
The dict.get() method returns the value of the given key. The get() method will not throw KeyError if the key is not present; instead, we get the None value or the default value that we pass in the get() method.
# Method returns dict def fetch_data(): output = {"Name": "Audi", "Release_Date": "2022", "Price": "$45000"} return output data = fetch_data() # Get the car Name print(data.get("Name"))Output
Audi Solution 2 – Check if the object is of type dictionary using typeAnother way is to check if the object is of type dictionary; we can do that using the type() method. This way, we can check if the object is of the correct data type before calling the get() method.
# Method returns dict def fetch_data(): output = {"Name": "Audi", "Release_Date": "2022", "Price": "$45000"} return output data = fetch_data() # Check if the object is dict if (type(data) == dict): print(data.get("Name")) softwares = "Norton, Bit Defender" if (type(softwares) == dict): print(softwares.get("Name")) else: print("The object is not dictionary and it is of type ", type(softwares))Output
Audi The object is not dictionary and it is of type <class 'str'> Solution 3 – Check if the object has get attribute using hasattrBefore calling the get() method, we can also check if the object has a certain attribute. Even if we call an external API which returns different data, using the hasattr() method, we can check if the object has an attribute with the given name.
# Method returns dict def fetch_data(): output = {"Name": "Audi", "Release_Date": "2022", "Price": "$45000"} return output data = fetch_data() # Check if the object has get attribute if (hasattr(data, 'get')): print(data.get("Name"))Output
Audi ConclusionThe AttributeError: ‘str’ object has no attribute ‘get’ occurs when you try to call the get() method on the string data type. The error also occurs if the calling method returns an string instead of a dictionary object.
We can resolve the error by calling the get() method on the dictionary object instead of an string. We can check if the object is of type dictionary using the type() method, and also, we can check if the object has a valid get attribute using hasattr() before performing the get operation.
ItsMyCode: [Solved] AttributeError: ‘float’ object has no attribute ‘get’
The AttributeError: ‘float’ object has no attribute ‘get’ mainly occurs when you try to call the get() method on the float data type. The attribute get() method is present in the dictionary and must be called on the dictionary data type.
In this tutorial, we will look at what exactly is AttributeError: ‘float’ object has no attribute ‘get’ and how to resolve this error with examples.
What is AttributeError: ‘float’ object has no attribute ‘get’?If we call the get() method on the float data type, Python will raise an AttributeError: ‘float’ object has no attribute ‘get’. The error can also happen if you have a method which returns an float instead of a dictionary.
Let us take a simple example to reproduce this error.
# Method return float instead of dict def fetch_data(): output = 44.55 return output data = fetch_data() print(data.get("price"))Output
AttributeError: 'float' object has no attribute 'get'In the above example, we have a method fetch_data() which returns an float instead of a dictionary.
Since we call the get() method on the float type, we get AttributeError.
We can also check if the variable type using the type() method, and using the dir() method, we can also print the list of all the attributes of a given object.
# Method return float instead of dict def fetch_data(): output = "Toyota Car" return output data = fetch_data() print("The type of the object is ", type(data)) print("List of valid attributes in this object is ", dir(data))Output
The type of the object is <class 'float'> List of valid attributes in this object is ['__abs__', '__add__', '__bool__', '__ceil__', '__class__', '__delattr__', '__dir__', '__divmod__', '__doc__', '__eq__', '__float__', '__floor__', '__floordiv__', '__format__', '__ge__', '__getattribute__', '__getformat__', '__getnewargs__', '__gt__', '__hash__', '__init__', '__init_subclass__', '__int__', '__le__', '__lt__', '__mod__', '__mul__', '__ne__', '__neg__', '__new__', '__pos__', '__pow__', '__radd__', '__rdivmod__', '__reduce__', '__reduce_ex__', '__repr__', '__rfloordiv__', '__rmod__', '__rmul__', '__round__', '__rpow__', '__rsub__', '__rtruediv__', '__set_format__', '__setattr__', '__sizeof__', '__str__', '__sub__', '__subclasshook__', '__truediv__', '__trunc__', 'as_integer_ratio', 'conjugate', 'fromhex', 'hex', 'imag', 'is_integer', 'real'] How to fix AttributeError: ‘float’ object has no attribute ‘get’?Let us see how we can resolve the error.
Solution 1 – Call the get() method on valid dictionaryWe can resolve the error by calling the get() method on the valid dictionary object instead of the float type.
The dict.get() method returns the value of the given key. The get() method will not throw KeyError if the key is not present; instead, we get the None value or the default value that we pass in the get() method.
# Method returns dict def fetch_data(): output = {"Name": "NordVPN", "Price": "22.22"} return output data = fetch_data() # Get the Price print(data.get("Price"))Output
22.22 Solution 2 – Check if the object is of type dictionary using typeAnother way is to check if the object is of type dictionary; we can do that using the type() method. This way, we can check if the object is of the correct data type before calling the get() method.
# Method returns dict def fetch_data(): output = {"Name": "NordVPN", "Price": "22.22"} return output data = fetch_data() # Get the Price if (type(data) == dict): print(data.get("Price")) else: print("The object is not dictionary and it is of type ", type(data))Output
22.22 Solution 3 – Check if the object has get attribute using hasattrBefore calling the get() method, we can also check if the object has a certain attribute. Even if we call an external API which returns different data, using the hasattr() method, we can check if the object has an attribute with the given name.

22.22 ConclusionThe AttributeError: ‘float’ object has no attribute ‘get’ occurs when you try to call the get() method on the floatdata type. The error also occurs if the calling method returns an float instead of a dictionary object.
We can resolve the error by calling the get() method on the dictionary object instead of an float. We can check if the object is of type dictionary using the type() method, and also, we can check if the object has a valid get attribute using hasattr() before performing the get operation.
ItsMyCode: [Solved] AttributeError: ‘list’ object has no attribute ‘get’
The AttributeError: ‘list’ object has no attribute ‘get’ mainly occurs when you try to call the get() method on the list data type. The attribute get() method is present in the dictionary and must be called on the dictionary data type.
In this tutorial, we will look at what exactly is AttributeError: ‘list’ object has no attribute ‘get’ and how to resolve this error with examples.
What is AttributeError: ‘list’ object has no attribute ‘get’?If we call the get() method on the list data type, Python will raise an AttributeError: ‘list’ object has no attribute ‘get’. The error can also happen if you have a method which returns an list instead of a dictionary.
Let us take a simple example to reproduce this error.
# Method return list of dict def fetch_data(): cars = [ {'name': 'Audi', 'price': 45000}, {'name': 'Ferrari', 'price': 450000}, {'name': 'BMW', 'price': 55000}, ] return cars data = fetch_data() print(data.get("name"))Output
AttributeError: 'list' object has no attribute 'get'In the above example, we have a method fetch_data() which returns an list of dictionary object instead of a dictionary.
Since we call the get() method directly on the list type, we get AttributeError.
We can also check if the variable type using the type() method, and using the dir() method, we can also print the list of all the attributes of a given object.
# Method return list of dict def fetch_data(): cars = [ {'name': 'Audi', 'price': 45000}, {'name': 'Ferrari', 'price': 450000}, {'name': 'BMW', 'price': 55000}, ] return cars data = fetch_data() print("The type of the object is ", type(data)) print("List of valid attributes in this object is ", dir(data))Output
The type of the object is <class 'list'> List of valid attributes in this object is ['__add__', '__class__', '__class_getitem__', '__contains__', '__delattr__', '__delitem__', '__dir__', '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__gt__', '__hash__', '__iadd__', '__imul__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__reversed__', '__rmul__', '__setattr__', '__setitem__', '__sizeof__', '__str__', '__subclasshook__', 'append', 'clear', 'copy', 'count', 'extend', 'index', 'insert', 'pop', 'remove', 'reverse', 'sort'] How to fix AttributeError: ‘list’ object has no attribute ‘get’?Let us see how we can resolve the error.
Solution 1 – Call the get() method on valid dictionaryWe can resolve the error by calling the get() method on the valid dictionary object instead of the list type.
Since the data has a valid dictionary object inside the list, we can loop through the list and use the get() method on the dictionary elements.
The dict.get() method returns the value of the given key. The get() method will not throw KeyError if the key is not present; instead, we get the None value or the default value that we pass in the get() method.
# Method return list of dict def fetch_data(): cars = [ {'name': 'Audi', 'price': 45000}, {'name': 'Ferrari', 'price': 450000}, {'name': 'BMW', 'price': 55000}, ] return cars data = fetch_data() for item in data: print(item.get("name"))Output
Audi Ferrari BMWWe can also use the generator expression, filter function to get specific dictionary element, or directly use the index of the list. Let us look at each of these with examples.
# Method return list instead of dict def fetch_data(): cars = [ {'name': 'Audi', 'price': 45000}, {'name': 'Ferrari', 'price': 450000}, {'name': 'BMW', 'price': 55000}, ] return cars data = fetch_data() # Generator expression to get specific element car_obj = next( (x for x in data if x['name'] == 'BMW'), {} ) print(car_obj) print("Car Name is ", car_obj.get("name")) print("Car Price is ", car_obj.get("price")) # Directly access the dictionary using the index of list print("The car name in index 0 is ", data[0].get("name"))Output
{'name': 'BMW', 'price': 55000} Car Name is BMW Car Price is 55000 The car name in index 0 is Audi Solution 2 – Check if the object is of type dictionary using typeAnother way is to check if the object is of type dictionary; we can do that using the type() method. This way, we can check if the object is of the correct data type before calling the get() method.
# Method return list of dict def fetch_data(): cars = [ {'name': 'Audi', 'price': 45000}, {'name': 'Ferrari', 'price': 450000}, {'name': 'BMW', 'price': 55000}, ] return cars # assigns the list of dict data = fetch_data() if (type(data) == dict): print(data.get("name")) else: print("The object is not dictionary and it is of type ", type(data)) # assign the index 0 dict my_car =data[0] if (type(my_car) == dict): print(my_car.get("name")) else: print("The object is not dictionary and it is of type ", type(my_car))Output
The object is not dictionary and it is of type <class 'list'> Audi Solution 3 – Check if the object has get attribute using hasattrBefore calling the get() method, we can also check if the object has a certain attribute. Even if we call an external API which returns different data, using the hasattr() method, we can check if the object has an attribute with the given name.
# Method return list of dict def fetch_data(): cars = [ {'name': 'Audi', 'price': 45000}, {'name': 'Ferrari', 'price': 450000}, {'name': 'BMW', 'price': 55000}, ] return cars # assigns the list of dict data = fetch_data() if (hasattr(data, 'get')): print(data.get("name")) else: print("The object does not have get attribute") # assign the index 0 dict my_car = data[0] if (hasattr(my_car, 'get')): print(my_car.get("name")) else: print("The object does not have get attribute")Output
The object does not have get attribute Audi ConclusionThe AttributeError: ‘list’ object has no attribute ‘get’ occurs when you try to call the get() method directly on the list data type. The error also occurs if the calling method returns an list instead of a dictionary object.
We can resolve the error by calling the get() method on the dictionary object by iterating the list instead of directly calling the get() method on an list. We can check if the object is of type dictionary using the type() method, and also, we can check if the object has a valid get attribute using hasattr() before performing the get operation.
MiTubo comes to macOS
I just released MiTubo 1.2. New in this version:
- As suggested by alphas12 in the comments, I added the author name in the YouTube search results.
- In the same results list, there's now a clickable link to the channel, which makes it easier to subscribe to it.
- Improve layout of some pages on narrow displays (though there's still much to be done!).
- Skip invoking youtube-dl if the video information is already encoded in the page HEAD meta properties.
- Remember the preferred playback resolution; this can be helpful on low bandwith connections.
- First macOS release!
While bringing in the macOS version, I updated the QScreenSaver library to support inhibiting the screensaver on macOS too.
I also tested the AppImage on openSUSE, and it seems to work fine there too. So, fewer and fewer people have valid excuses not to try out MiTubo!

Python Morsels: Appreciating Python's match-case by parsing Python code
Python's match-case blocks are complex structural pattern matching tools that are often more hassle than they're worth. But they're great for parsing abstract syntax trees.
Table of contents
- Why remove dataclasses?
- Oh, that's what that tool is for?
- Using "or patterns" to match multiple sub-patterns
- Conditional patterns with guard clauses
- Structural pattern matching visually describes the structure of objects
- When writing parsers and matchers, consider match-case
First let's briefly talk about why I made this tool.
Why would anyone want to convert a dataclass into "not a dataclass"?
There are trade offs with using dataclasses: performance concerns (which don't usually matter) and edge cases where things get weird (__slots__ and slots=True are both finicky). But my reason for creating this dataclass to regular class converter was to help me better teach dataclasses. Seeing the equivalent code for a dataclass helps us appreciate what dataclasses do for us.
Okay let's dive into match-case.

Real Python: Effective Python Testing With Pytest
Testing your code brings a wide variety of benefits. It increases your confidence that the code behaves as you expect and ensures that changes to your code won’t cause regressions. Writing and maintaining tests is hard work, so you should leverage all the tools at your disposal to make it as painless as possible. pytest is one of the best tools that you can use to boost your testing productivity.
In this tutorial, you’ll learn:
- What benefits pytest offers
- How to ensure your tests are stateless
- How to make repetitious tests more comprehensible
- How to run subsets of tests by name or custom groups
- How to create and maintain reusable testing utilities
Free Bonus: 5 Thoughts On Python Mastery, a free course for Python developers that shows you the roadmap and the mindset you’ll need to take your Python skills to the next level.
How to Install pytestTo follow along with some of the examples in this tutorial, you’ll need to install pytest. As most Python packages, pytest is available on PyPI. You can install it in a virtual environment using pip:
PS> python -m venv venv PS> .\venv\Scripts\activate (venv) PS> python -m pip install pytest $ python -m venv venv $ source venv/bin/activate (venv) $ python -m pip install pytestThe pytest command will now be available in your installation environment.
What Makes pytest So Useful?If you’ve written unit tests for your Python code before, then you may have used Python’s built-in unittest module. unittest provides a solid base on which to build your test suite, but it has a few shortcomings.
A number of third-party testing frameworks attempt to address some of the issues with unittest, and pytest has proven to be one of the most popular. pytest is a feature-rich, plugin-based ecosystem for testing your Python code.
If you haven’t had the pleasure of using pytest yet, then you’re in for a treat! Its philosophy and features will make your testing experience more productive and enjoyable. With pytest, common tasks require less code and advanced tasks can be achieved through a variety of time-saving commands and plugins. It’ll even run your existing tests out of the box, including those written with unittest.
As with most frameworks, some development patterns that make sense when you first start using pytest can start causing pains as your test suite grows. This tutorial will help you understand some of the tools pytest provides to keep your testing efficient and effective even as it scales.
Less BoilerplateMost functional tests follow the Arrange-Act-Assert model:
- Arrange, or set up, the conditions for the test
- Act by calling some function or method
- Assert that some end condition is true
Testing frameworks typically hook into your test’s assertions so that they can provide information when an assertion fails. unittest, for example, provides a number of helpful assertion utilities out of the box. However, even a small set of tests requires a fair amount of boilerplate code.
Imagine you’d like to write a test suite just to make sure that unittest is working properly in your project. You might want to write one test that always passes and one that always fails:
# test_with_unittest.py from unittest import TestCase class TryTesting(TestCase): def test_always_passes(self): self.assertTrue(True) def test_always_fails(self): self.assertTrue(False)You can then run those tests from the command line using the discover option of unittest:
(venv) $ python -m unittest discover F. ====================================================================== FAIL: test_always_fails (test_with_unittest.TryTesting) ---------------------------------------------------------------------- Traceback (most recent call last): File "...\effective-python-testing-with-pytest\test_with_unittest.py", line 10, in test_always_fails self.assertTrue(False) AssertionError: False is not true ---------------------------------------------------------------------- Ran 2 tests in 0.006s FAILED (failures=1)As expected, one test passed and one failed. You’ve proven that unittest is working, but look at what you had to do:
- Import the TestCase class from unittest
- Create TryTesting, a subclass of TestCase
- Write a method in TryTesting for each test
- Use one of the self.assert* methods from unittest.TestCase to make assertions
That’s a significant amount of code to write, and because it’s the minimum you need for any test, you’d end up writing the same code over and over. pytest simplifies this workflow by allowing you to use normal functions and Python’s assert keyword directly:

www @ Savannah: New Article by Richard Stallman
The GNU Education Team has published a new article by Richard Stallman on the threats of Big Tech in the field of education.
Human Rights Watch studied 164 software programs and web sites recommended by various governments for schools to make students use. It found that 146 of them gave data to advertising and tracking companies.
The researchers were thorough and checked for various snooping methods, including fingerprinting of devices to identify users. The targets of the investigation were not limited to programs and sites specifically “for education;” they included, for instance, Zoom and Microsoft Teams.
I expect that each program collected personal data for its developer. I'm not sure whether the results counted that, but they should. Once the developer company gets personal data, it can provide that data to advertising profilers, as well as to other companies and governments, and it can engage directly in manipulation of students and teachers.
The recommendations Human Rights Watch makes follow the usual approach of regulating the use of data once collected. This is fundamentally inadequate; personal data, once collected, will surely be misused.
The only approach that makes it possible to end massive surveillance starts with demanding that the software be free. Then users will be able to modify the software to avoid giving real data to companies.
Python for Beginners: Append Dictionary to CSV File in Python
CSV files are one of the most efficient tools to store structured, tabular data. Sometimes, we might need to append data to the CSV file from a python dictionary. In this article, we will discuss how we can append the values in a dictionary to a CSV file in python.
Append Dictionary to CSV File Using csv.writer()You can append a dictionary to CSV file using CSV.writer() method and CSV.writerow() method. For this, we will first open the CSV file in append mode using the open() function. The open() function takes the filename as its first input argument and the literal “a” as its second input argument to denote that the file is opened in the append mode.
After opening the file, we will create a CSV writer object using the CSV.writer() function. The CSV.writer() function takes the file object containing the CSV file as its input argument and returns a writer object.
After creating the writer object, we will append the dictionary to the CSV file using the writerow() method. The writerow() method, when invoked on a writer object, takes the values in the dictionary as its input argument and appends it to the CSV file.
After execution of the writerow() method, you must close the CSV file using the close() method. Otherwise, the changes won’t be saved in the CSV file. The source code for this approach to append a dictionary to a CSV file is given below.
import csv myFile = open('Demo.csv', 'r+') print("The content of the csv file before appending is:") print(myFile.read()) myDict = {'Roll': 4, 'Name': 'Joel', 'Language': 'Golang'} print("The dictionary is:") print(myDict) writer = csv.writer(myFile) writer.writerow(myDict.values()) myFile.close() myFile = open('Demo.csv', 'r') print("The content of the csv file after appending is:") print(myFile.read())Output:
The content of the csv file before appending is: Roll,Name,Language 1,Aditya,Python 2,Sam, Java 3, Chris, C++ The dictionary is: {'Roll': 4, 'Name': 'Joel', 'Language': 'Golang'} The content of the csv file after appending is: Roll,Name,Language 1,Aditya,Python 2,Sam, Java 3, Chris, C++ 4,Joel,Golang Append Dictionary to CSV File using csv.DictWriter()Instead of using the csv.writer() method, we can use the csv.DictWriter() function along with the csv.writerow() method to append a python dictionary to csv file. The approach is almost similar to the approach using the csv.writer() method with the following differences.
- Instead of the csv.writer() method, we will use the csv.DictWriter() method. The DictWriter() method takes the file object containing the csv file as its input argument and returns a DictWriter object.
- When the writerow() method is executed on the DictWriter object, it takes a dictionary as the input argument instead of the values in the dictionary.
The python code to append a dictionary to a csv file using csv.DictWriter() is as follows.
import csv myFile = open('Demo.csv', 'r+') print("The content of the csv file before appending is:") print(myFile.read()) myDict = {'Roll': 4, 'Name': 'Joel', 'Language': 'Golang'} print("The dictionary is:") print(myDict) writer = csv.DictWriter(myFile, fieldnames=list(myDict.keys())) writer.writerow(myDict) myFile.close() myFile = open('Demo.csv', 'r') print("The content of the csv file after appending is:") print(myFile.read())Output:
The content of the csv file before appending is: Roll,Name,Language 1,Aditya,Python 2,Sam, Java 3, Chris, C++ The dictionary is: {'Roll': 4, 'Name': 'Joel', 'Language': 'Golang'} The content of the csv file after appending is: Roll,Name,Language 1,Aditya,Python 2,Sam, Java 3, Chris, C++ 4,Joel,Golang ConclusionIn this article, we have discussed two ways to append a dictionary to csv file in python. In these approaches, the dictionary will be appended irrespective of whether it has same number of items as compared to the columns in the csv file or it has the same keys as compared to the column names in the csv file. Thus it advised to make sure that the dictionary should have the same number of keys as compared to the columns in the csv file. Also You should make sure that the order of columns of the csv file should be same as the order of the keys present in the dictionary. Otherwise, the data appended to the csv file will become inconsistent and will lead to errors.
