Planet Debian - Wed, 2024-04-17 11:00

I am happy to report that the megactl package, useful to fetch RAID status when using the LSI Megaraid controller, now is available in Debian. It passed NEW a few days ago, and is now available in unstable, and probably showing up in testing in a weeks time. The new version should provide Appstream hardware mapping and should integrate nicely with isenkram.

Real Python: How to Format Floats Within F-Strings in Python

Planet Python - Wed, 2024-04-17 10:00

You’ll often need to format and round a Python float to display the results of your calculations neatly within strings. In earlier versions of Python, this was a messy thing to do because you needed to round your numbers first and then use either string concatenation or the old string formatting technique to do this for you.

Since Python 3.6, the literal string interpolation, more commonly known as a formatted string literal or f-string, allows you to customize the content of your strings in a more readable way.

An f-string is a literal string prefixed with a lowercase or uppercase letter f and contains zero or more replacement fields enclosed within a pair of curly braces {...}. Each field contains an expression that produces a value. You can calculate the field’s content, but you can also use function calls or even variables.

While most strings have a constant value, f-strings are evaluated at runtime. This makes it possible for you to pass different data into the replacement fields of the same f-string and produce different output. This extensibility of f-strings makes them a great way to embed dynamic content neatly inside strings. However, even though f-strings have largely replaced the earlier methods, they do have their short-comings.

For example, one of the most common attacks performed on a relational database is a SQL injection attack. Often, users provide parameters to SQL queries, and if the query is formed within an f-string, it may be possible to damage a database by passing in rogue commands. F-strings can also be used in a denial-of-service attack by attacking Python’s logging module code.

In older versions of Python, f-strings had a number of other limitations that were only fixed with Python version 3.12. This version is used throughout this tutorial.

Take a look at the example below. It shows you how to embed the result of a calculation within an f-string:

Python >>> f"One third, expressed as a float is: {1 / 3}" 'One third, expressed as a float is: 0.3333333333333333' Copied!

Without any explicit rounding, once an expression has produced its value it’ll be inserted into the string using a default number of decimal places. Here, the result is shown to sixteen decimal places, which, in most cases, is more precision than you’ll ever need. So you’ll likely want to round your final answer to a more practical number of digits.

In this tutorial, you’ll learn how to use a Python f-string to format floats to meet your requirements.

Interactive Quiz

Format Floats Within F-Strings

In this quiz, you'll test your understanding of how to format floats within f-strings in Python. This knowledge will let you control the precision and appearance of floating-point numbers when you incorporate them into formatted strings.

How to Format and Round a Float Within a Python F-String

To format a float for neat display within a Python f-string, you can use a format specifier. In its most basic form, this allows you to define the precision, or number of decimal places, the float will be displayed with.

The code below displays the same calculation as before, only it’s displayed more neatly:

Python >>> f"One third, rounded to two decimal places is: {1 / 3:.2f}" 'One third, rounded to two decimal places is: 0.33' Copied!

To use Python’s format specifiers in a replacement field, you separate them from the expression with a colon (:). As you can see, your float has been rounded to two decimal places. You achieved this by adding the format specifier .2f into the replacement field. The 2 is the precision, while the lowercase f is an example of a presentation type. You’ll see more of these later.

Note: When you use a format specifier, you don’t actually change the underlying number. You only improve its display.

Python’s f-strings also have their own mini-language that allows you to format your output in a variety of different ways. Although this tutorial will focus on rounding, this is certainly not the only thing you can use them for. As you’ll see later, their mini-language is also used in other string formatting techniques.

In addition to displaying the result of calculations, the precision part of a format specifier can also be applied directly to variables and the return values of function calls:

Python >>> def total_price(cost): ... return cost * 1.2 ... >>> cost_price = 1000 >>> tax = 0.2 >>> f"£{1000:,.2f} + £{cost_price * tax:,.2f} = £{total_price(cost_price):,.2f}" '£1,000.00 + £200.00 = £1,200.00' Copied!

This time, you’ve used multiple replacement fields in the same string. The first one formats a literal number, the second formats the result of a calculation, while the third formats the return value from a function call. Also, by inserting a comma (,) before the decimal point (.) in the format specifier, you add a thousands separator to your final output.

In everyday use, you display numbers with a fixed amount of decimals, but when performing scientific or engineering calculations, you may prefer to format them using significant figures. Your results are then assumed to be accurate to the number of significant figures you display them with.

If you want to round numbers to significant figures, you use the lowercase letter g in the format specifier. You can also use an uppercase G, but this automatically switches the format to scientific notation for large numbers.

Suppose you have a circle with a radius of 10.203 meters. To work out the area, you could use this code:

PyBites: OpenStreetMaps, Overpass API and Python

Planet Python - Wed, 2024-04-17 08:58

OpenStreetMaps (OSM) is known for being an open source project that allows people to browse the world map and to plan routes. However it is more than that. Among others it provides a read-only API that allows users to query for very diverse map data: Overpass API

Data structure of OSM

To understand the structure of the queries, we first need to understand how OSM saves its data. OSM uses basic data structures: node, way, and relation. Each element can have multiple tags, which consist of a key-value pair and they help specify the features of each element.

Nodes also save a latitude and longitude, indicating where the node is located on the world. Ways contain a list of the nodes contained in the way. Finally, relations are groups of nodes, ways and relations defining a logical relationship for this elements, for example being part of the same street, neighbourhood, city, postal code area, etc.

If we go to https://www.openstreetmap.org/, right-click on some point of the map and then click on Query Features, we get a list of the elements of the area. By clicking on one of them, we can explore it’s characteristics. As an example, we can explore the node 1918872432, which we can see on the left picture. Looking at the data we can see that it is located at longitude 52.5024783 and latitude 13.4155630. On the tags we can see it has the name Oranienplatz and among others it contains a bench and a bin. The key highway contains the value bus_stop, which tells us it is a bus stop.

If we explore the way 1228261444 (right picture) we can see a list of all the nodes it contains. In addition on the key highway we can see it’s of the type footway, telling us it’s a way intended for pedestrians. In addition we can see that it is a lit way.

Many keywords like highway are normalized. As an example, we can find a list of standardized values for highway here.

Overpass Queries Querying a single element

We can query the previous information using Overpass QL. For the query to get the information about the way 1228261444 we use way(1228261444). The default output format is in xml, so if we want to have it in json, we need to add [out:json] in front of it. Other possible formats are csv, for which we need to define the list of columns for it to work. We mark the end of the query with an out, so the complete query is:

[out:json]; way(1228261444); out;

To execute the query we need to run it against an instance, thus the complete URL looks like this:

https://overpass-api.de/api/interpreter?data=[out:json];way(1228261444);out;

We can copy the URL directly on the browser, or we can use wget to see the result:

wget -O my_file_name.osm "https://overpass-api.de/api/interpreter?data=[out:json];way(1228261444);out;"

To query a single node or relation works in a parallel way.

Output format { "version": 0.6, "generator": "Overpass API 0.7.61.5 4133829e", "osm3s": { "timestamp_osm_base": "2024-03-06T20:54:14Z", "copyright": "The data included in this document is from www.openstreetmap.org. The data is made available under ODbL." }, "elements": [ { "type": "way", "id": 1228261444, "nodes": [ 9010521154, 9010521155, 11390038869, 11390038870, 9394918823, 9394918824, 4613855449, 11390038871, 11390038872, 11390038873, 9394918822 ], "tags": { "footway": "sidewalk", "highway": "footway", "lit": "yes", "surface": "paving_stones" } } ] }

Here we can see two main blocks: the first with metadata like the version or the timestamp, and the second one with a list of the elements found with the query. Even if we queried for one specific element of type way, we still get it as a set formatted as list with length 1.

Querying many elements

If we don’t want the information of one singe way, but the information of all ways in an area, we need to change the query a little bit:

[out:json]; way(52.49505089381484,13.401961459729343,52.509912981033516,13.411502705004548); out;

Here, instead of requesting one single way, we put 4 coordinates in the parenthesis: boundaries in the south, west, north and east.

This returns a set of all the ways contained in the bounding box defined by the given coordinates.

It is not always needed to know the coordinates to get information for an area. With the query

[out:json]; area[name="Zürich"]; out;

we get all areas called Zürich. In this example we can see that we can use special characters without problem. Most interestingly are both square parentheses behind area [name=”Zürich”]. This is a filter where we only get the areas that contain a tag with key name and value Zürich.

We can use more than one filter, for example to get only the element representing the city Zürich, in contrast to the canton Zürich. In that case we can just place them one after another like this:

[out:json]; area[name=”Zürich”][place=”city”]; out;

We can filter by elements containing a certain tag independently from it’s value.

[out:json]; area[name=”Zürich”][place]; out;

This returns a set of all areas containing the tag place, which in this case contains the same element as above.

Subqueries

We can use the area we got in the previous query to get a set of certain elements inside said area. For example, if we want to get all public toilets in Zürich, we can use the following query:

[out:json]; area[name="Zürich"][place="city"]; node[amenity="toilets"](area); out;

First we get the area corresponding to the city Zürich, and then we get all nodes whose tag key amenity contains the value toilets. By passing the area between the round parenthesis we limit the set of nodes to the previous area.

The tag amenity describes a large number of important facilities from cafés, public bookcases, benches, vending machines, ATMs, etc.

Other useful tag names to find interesting places are tourism and historic.

TIL: there is also a value for public baking ovens, baking_oven. Apparently there are 2 of those which Zürich, which looks to me like a good reason to visit that city again. Seriously, how awesome is that?

Using overpass in Python

There are two ways to execute overpass queries with python that we will explore. One possibility is using the library and the other the library overpass-api-python-wrapper.

Requests

Example:

import requests overpass_url = 'https://overpass-api.de/api/interpreter' overpass_query = ''' [out:json]; area[name="Zürich"][place="city"]; node[amenity="toilets"](area); out; ''' response = requests.get(overpass_url, params={'data': overpass_query})

This way we send to the overpass interpreter the query in overpass_query and save the result in the variable response. If no error happened, response.text contains the data as string so we can decode it with:

decoded_data =json.loads(response.text)

If we had requested the information in xml or csv format, we would decode it accordingly.

Overpass-api-python-wrapper

The overpass-api-python-wrapper allows us to execute queries in a more concise and elegant way. First we need to initialize an overpass object.

import overpass api = overpass.API(endpoint="https://overpass.myserver/interpreter", timeout=25)

All parameters are optional and the default values are the ones shown here.

query = 'area[name="Zürich"][place="city"];node[amenity="toilets"](area);' response = api.get(query, responseformat='json')

By default, response contains a dictionary representing the returned json object, however we can define the output format with the parameter responseformat. With this query, the response is

{ "features": [ { "geometry": { "coordinates": [ 8.534562, 47.350221 ], "type": "Point" }, "id": 75743585, "properties": { "amenity": "toilets", "capacity": "4", "check_date:wheelchair": "2022-06-06", "fee": "no", "name": "Landiwiese", "opening_hours": "24/7", "operator": "Z\u00fcriWC", "unisex": "yes", "wheelchair": "no" }, "type": "Feature" }, etc }

If we use xml as format, response will be a string, and with csv it will be a list.

Other Useful tools:

We can find a complete manual on Overpass QL here, where we can read about more awesome possibilities that Overpass has to offer to us.

You can also try out queries with overpass-turbo. However it will only display the returned nodes on the map, but you can also get the returned response as text in the tab Data.

Finally, you can find another cool tutorial for using overpass with python here. In this case, the author shows us new possibilities with overpass, including how to plot the queried data in plots.

I hope you could awake your curiosity about the potential that OpenStreetMaps and Overpass offers. For me in meant not only to learn about a powerful tool, but while exploring it and playing with it it allowed me to learn more about the possibilities our cities and towns have to offer to us. Did you know that there are public showers, including in some train stations? Or that there are public ovens?

What I finally have to say is: keep calm and keep building cool stuff!

Talking Drupal: Skills Upgrade #7

Planet Drupal - Wed, 2024-04-17 04:00

Welcome back to “Skills Upgrade” a Talking Drupal mini-series following the journey of a D7 developer learning D10. This is episode 7.

Topics
  • Review Chad's goals for the previous week

    • Test Example
    • Set up phpunit.xml
    • Start with FrontPageLinkTest.php
  • Review Chad's questions

    • In the testing_example module, the file "src/Controller/TestingExampleController.php" has a function for simpletestDescription(). Is this an outdated artifact that should have been removed at some point? The module itself doesn't appear to use Simpletest elsewhere and appears to only rely on PHPUnit.
    • What do you recommend for the minimal code structure to include for any given test type? Is the Testing Example module an ideal model or are there other resources I should review? The testing reference from Selwyn was helpful.
    • In the "FrontPageLinkDependenciesTest.php" setUp() function, the createContentType() function is called without specifying the type. Is that set somewhere else? I may have overlooked it. Nevermind—it's set using randomMachineName() in the createContentType() function. Is there anything extra or standard to write in tests for drupal.org?
  • Tasks for the upcoming week

    • Smart Date - Martin (maintainer) to review promptly, I've already chatted with him about it. Create a new functional test: "submit a range with an end time before the start and validate that an error is returned"
      • Create an issue in the Smart Date queue and assign to yourself.
      • Create an issue fork.
      • Check out the issue fork locally.
      • Write (and test) the test locally.
      • Commit and push to the issue fork.
      • Mark issue as "Needs review".
      • Ask someone to review - if all looks good, the reviewer will mark as RBTC.

Dirk Eddelbuettel: RcppArmadillo 0.12.8.2.1 on CRAN: Micro Fix

Planet Debian - Tue, 2024-04-16 22:00

Armadillo is a powerful and expressive C++ template library for linear algebra and scientific computing. It aims towards a good balance between speed and ease of use, has a syntax deliberately close to Matlab, and is useful for algorithm development directly in C++, or quick conversion of research code into production environments. RcppArmadillo integrates this library with the R environment and language–and is widely used by (currently) 1135 other packages on CRAN, downloaded 33.7 million times (per the partial logs from the cloud mirrors of CRAN), and the CSDA paper (preprint / vignette) by Conrad and myself has been cited 579 times according to Google Scholar.

Yesterday’s release accommodates reticulate by suspending a single test that now ‘croaks’ creating a reverse-dependency issue for that package. No other changes were made.

The set of changes since the last CRAN release follows.

Changes in RcppArmadillo version 0.12.8.2.1 (2024-04-15)
  • One-char bug fix release commenting out one test that upsets reticulate when accessing a scipy sparse matrix

Courtesy of my CRANberries, there is a diffstat report relative to previous release. More detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the Rcpp R-Forge page.

If you like this or other open-source work I do, you can sponsor me at GitHub.

Python Engineering at Microsoft: Glow up! A new look for Python Reference documentation on Microsoft Learn

Planet Python - Tue, 2024-04-16 17:41

Today, we’re excited to announce a new, improved experience for Python library reference documentation on Microsoft Learn, formerly Microsoft Docs. The new experience is now available for all Microsoft Python libraries on Learn, such as the Azure SDK for Python. In this blog post, we take a closer look at the specific changes made and how they improve the overall experience and accessibility of Python reference documentation on Learn.

Change Summary

The key changes made to Python reference documentation on Learn were improving the navigation experience with the table of contents (TOC), the organization of in-page content, and in-page navigation via the right rail. When combined, these three key changes greatly improve the experience of finding information in Python reference on Learn.

Table of Contents (TOC)

If you’ve used reference documentation before, you’ll know that the TOC serves as a uniquely pivotal tool for navigation between pages. Reference documentation, unlike conceptual articles and tutorials, rarely links together in an easy-to-follow way. This means that the TOC is often the only way for cross-page navigation in reference documentation, making it a key priority for us to get right.

TOC – Before

Previously, the table of contents for Python Reference documentation on Learn had a redundant layer of navigation for package names (in the screenshot below, the azure-storage-blob node), which added confusion for users looking to navigate deeper into the documentation. In addition, the table of contents had package prefixes attached to every item. This led to a cluttered experience, with some items in the TOC taking up two lines of space, further impacting readability and accessibility.

 

TOC – After

The new TOC design removes the package name overview page and trims the package prefix from TOC items, making it easier to scan and navigate. If you’ve bookmarked a package name overview page, don’t worry, as you’ll be redirected to the package overview page automatically.

 

In-Page Right Rail

The in-page right rail is a key part of reference documentation, allowing you to navigate in-page and quickly jump to different sections.

In-Page Right Rail – Before

Before, the right rail wasn’t “sticky”, meaning that once users scrolled on the page, the rail wouldn’t follow them, and the entire right side of the screen would be unused space. Additionally, the right rail links only covered H2 content on the page, resulting in a right rail that didn’t clarify any major details on the page. Finally, the right rail would be collapsed beyond four items, leading to extra effort from the user to see all of the H2 sections on the page. We recognize this design wasn’t consistent with the ways that other Python libraries design their documentation and made updates to better align with design patterns and expectations.

 

In-Page Right Rail – After

The enhanced experience adds an individually scrollable, sticky right rail with details down to H3s, giving much more detail into what content the page has. The right rail additionally has active highlighting for the current item on the screen, making it easier for you to understand your current position relative to other content.

Parameter, Return, and Exception Organization

While the first two major feature changes focus on both overall and in-page navigation, we also identified an opportunity to improve in-page organization as well. When you’re looking at our reference documentation, being able to easily identify key information such as parameters, return values, and exceptions is crucial.

In-Page Organization – Before

Before the updates, these details were listed but not clearly separated between classes, leading to a confusing experience where it’s not clear where items started or ended. Additionally, as a result of the formatting of these values, a significant amount of vertical space was used, leading to a lot of scrolling to find the information needed. Lastly, required parameters, default values, and keyword-only parameters weren’t clearly highlighted to follow accessibility best practices, resulting in extra effort to find crucial information.

In-Page Organization – After

The new experience organizes parameters, return values, and exceptions into easy-to-scan tables. By using tables, default values, required tags, and types are clearly indicated. The end result is a cleaner and easier-to-use experience for all developers when scrolling through our documentation.

 

Conclusion

In short, the new Python reference documentation experience on Learn is a major improvement for any developer using Microsoft’s Python libraries. The new TOC, in-page right rail, and in-page organization changes make finding information easier, with an added visual upgrade. We’re excited to continue optimizing the Python developer experience across all of our libraries and tools.

We hope you enjoy the changes! If you have any thoughts, you can leave feedback in the Azure SDK for Python GitHub repo.

A Lazy and Flippant Classification of Programming Languages

“When talking flippantly about programming languages, it’s sometimes useful to glob a bunch of them together based on characteristics, whether superficial or not.

Python Morsels: Python Big O: the time complexities of different data structures in Python

Planet Python - Tue, 2024-04-16 11:00

The time complexity of common operations on Python's many data structures.

  2. List 📋
  3. Double-Ended Queue ↔️
  4. Dictionary 🗝️
  5. Set 🎨
  6. Counter 🧮
  7. Heap / Priority Queue ⛰️

  11. Beware of Loops-in-Loops! 🤯
  12. Mind Your Data Structures 🗃️

Time Complexity ⏱️

Time complexity is one of those Computer Science concepts that's scary in its purest form, but often fairly practical as a rough "am I doing this right" measurement.

In the words of Ned Batchelder, time complexity is all about "how your code slows as your data grows".

Time complexity is usually discussed in terms of "Big O" notation. This is basically a way to discuss the order of magnitude for a given operation while ignoring the exact number of computations it needs. In "Big O" land, we don't care if something is twice as slow, but we do care whether it's n times slower where n is the length of our list/set/slice/etc.

Here's a graph of the common time complexity curves:

Remember that these lines are simply about orders of magnitude. If an operation is on the order of n, that means 100 times more data will slow things down about 100 times. If an operation is on the order of n² (that's n*n), that means 100 times more data will slow things down 100*100 times.

I usually think about those curves in terms of what would happen if we suddenly had 1,000 times more data to work with:

  • O(1): no change in time (constant time!)
  • O(log n): ~10 times slow down
  • O(n): 1,000 times slow down
  • O(n log n): 10,000 times slow down
  • O(n²): 1,000,000 times slow down! 😲

With that very quick recap behind us, let's take a look at the relative speeds of all common operations on each of Python's data structures.

Real Python: Using raise for Effective Exceptions

Planet Python - Tue, 2024-04-16 10:00

In your Python journey, you’ll come across situations where you need to signal that something is going wrong in your code. For example, maybe a file doesn’t exist, a network or database connection fails, or your code gets invalid input. A common approach to tackle these issues is to raise an exception, notifying the user that an error has occurred. That’s what Python’s raise statement is for.

Learning about the raise statement allows you to effectively handle errors and exceptional situations in your code. This way, you’ll develop more robust programs and higher-quality code.

In this video course, you’ll learn how to:

  • Raise exceptions in Python using the raise statement
  • Decide which exceptions to raise and when to raise them in your code
  • Explore common use cases for raising exceptions in Python
  • Apply best practices for raising exceptions in your Python code

Balint Pekker: Enhancing Drupal with GitHub Actions

Planet Drupal - Tue, 2024-04-16 06:49
When it comes to Drupal development, GitHub Actions offers invaluable assistance in automating repetitive tasks, standardizing your processes, and enhancing code quality. By defining workflows as code in YAML files that can react to various events, it provides flexible customization and scalability. Pre-built actions can handle common tasks like building and testing code, while custom actions can be tailored to project-specific requirements. Let's explore some of the best practices along with examples of actions you could use in your next Drupal project.
