After discussing how to avoid entity ID conflicts in the previous article, we are finally ready to start migrating content. The first entity we will focus on is files, covering both public and private file migrations. We will share tips and hacks related to performance optimizations and discuss how to handle files hosted outside of Drupal.

When you work on a team, it's useful to have notifications go to a chat room where you can coordinate any necessary action. Reviewing a comment before publishing, seeing stories as they are written, getting notified of new orders are the kinds of things we like having in a shared room.

Losing access to your Drupal admin account can be a stressful experience. Your admin password is the key to maintaining and managing your website and being locked out can halt your ability to make critical updates or manage content. Fortunately, there are several methods to regain access, whether you're using Drupal 7 or the latest version of the system. This guide will walk you through the possible options to reset your password and return to your web page.

After working with Python for a while, you’ll eventually come across two seemingly similar terms: expression and statement. When you browse the official documentation or dig through a Python-related thread on an online forum, you may get the impression that people use these terms interchangeably. That’s often true, but confusingly enough, there are cases when the expression vs statement distinction becomes important.

So, what’s the difference between expressions and statements in Python?

Expression vs Statement in Python: What's the Difference?

In this quiz, you'll test your understanding of Python expressions vs statements. Knowing the difference between these two is crucial for writing efficient and readable Python code.

In Short: Expressions Have Values and Statements Cause Side Effects

When you open the Python glossary, you’ll find the following two definitions:

Expression: A piece of syntax which can be evaluated to some value. (…) (Source)

Statement: A statement is part of a suite (a “block” of code). A statement is either an expression or one of several constructs with a keyword, (…) (Source)

Well, that isn’t particularly helpful, is it? Fortunately, you can summarize the most important facts about expressions and statements in as little as three points:

1. All instructions in Python fall under the broad category of statements.
2. By this definition, all expressions are also statements—sometimes called expression statements.
3. Not every statement is an expression.

In a technical sense, every line or block of code is a statement in Python. That includes expressions, which represent a special kind of statement. What makes an expression special? You’ll find out now.

Expressions: Statements With Values

Essentially, you can substitute all expressions in your code with the computed values, which they’d produce at runtime, without changing the overall behavior of your program. Statements, on the other hand, can’t be replaced with equivalent values unless they’re expressions.

Consider the following code snippet:

Python >>> x = 42 >>> y = x + 8 >>> print(y) 50 Copied!

In this example, all three lines of code contain statements. The first two are assignment statements, while the third one is a call to the print() function.

When you look at each line more closely, you can start disassembling the corresponding statement into subcomponents. For example, the assignment operator (=) consists of the parts on the left and the right. The part to the left of the equal sign indicates the variable name, such as x or y, and the part on the right is the value assigned to that variable.

The word value is the key here. Notice that the variable x is assigned a literal value, 42, that’s baked right into your code. In contrast, the following line assigns an arithmetic expression, x + 8, to the variable y. Python must first calculate or evaluate such an expression to determine the final value for the variable when your program is running.

Arithmetic expressions are just one example of Python expressions. Others include logical expressions, conditional expressions, and more. What they all have in common is a value to which they evaluate, although each value will generally be different. As a result, you can safely substitute any expression with the corresponding value:

Python >>> x = 42 >>> y = 50 >>> print(y) 50 Copied!

This short program gives the same result as before and is functionally identical to the previous one. You’ve calculated the arithmetic expression by hand and inserted the resulting value in its place.

Note that you can evaluate x + 8, but you can’t do the same with the assignment y = x + 8, even though it incorporates an expression. The whole line of code represents a pure statement with no intrinsic value. So, what’s the point of having such statements? It’s time to dive into Python statements and find out.

Statements: Instructions With Side Effects

Statements that aren’t expressions cause side effects, which change the state of your program or affect an external resource, such as a file on disk. For example, when you assign a value to a variable, you define or redefine that variable somewhere in Python’s memory. Similarly, when you call print(), you effectively write to the standard output stream (stdout), which, by default, displays text on the screen.

Note: While statements encompass expressions, most people use the word statement informally when they refer to pure statements or instructions with no value.

Okay. You’ve covered statements that are expressions and statements that aren’t expressions. From now on, you can refer to them as pure expressions and pure statements, respectively. But it turns out there’s a middle ground here.

In the second episode of The DropTimes' "Splash Award Finalists" series, explore how Axelerant’s innovative work for the Internal Displacement Monitoring Centre (IDMC) has transformed its digital platform. Learn how this project tackles global displacement challenges and why it’s a contender for the 'Not-for-Profit' category at the Splash Awards Asia.

The theme "Ceratopsian" by Elise Couper has been selected as the default theme for Debian 13 "trixie". The theme is inspired by Trixie's (the fictional character from Toy Story) frill and is also influenced by a previously used theme called "futurePrototype" by Alex Makas.

After the Debian Desktop Team made the call for proposing themes, a total of six choices were submitted. The desktop artwork poll was open to the public, and we received 2817 responses ranking the different choices, of which Ceratopsian has been ranked as the winner among them.

We'd like to thank all the designers that have participated and have submitted their excellent work in the form of wallpapers and artwork for Debian 13.

Congratulations, Elise, and thank you very much for your contribution to Debian!

I posted a Python tidbit about checking if a string consists entirely of zeros and ones:

I got a bunch of replies suggesting other ways. I wanted to post those, but I also wanted to check if they were right. A classic testing structure would have required putting them all in functions, etc, which I didn’t want to bother with.

So I cobbled together a test harness for them (also in a gist if you want):

GOOD = [
    "",
    "0",
    "1",
    "000000000000000000",
    "111111111111111111",
    "101000100011110101010000101010101001001010101",
]

BAD = [
    "x",
    "nedbat",
    "x000000000000000000000000000000000000",
    "111111111111111111111111111111111111x",
    "".join(chr(i) for i in range(10000)),
]

TESTS = """
    # The original checks
    all(c in "01" for c in s)
    set(s).issubset({"0", "1"})
    set(s) <= {"0", "1"}
    re.fullmatch(r"[01]*", s)
    s.strip("01") == ""
    not s.strip("01")

    # Using min/max
    "0" <= min(s or "0") <= max(s or "1") <= "1"
    not s or (min(s) in "01" and max(s) in "01")
    ((ss := sorted(s or "0")) and ss[0] in "01" and ss[-1] in "01")

    # Using counting
    s.count("0") + s.count("1") == len(s)
    (not (ctr := Counter(s)) or (ctr["0"] + ctr["1"] == len(s)))

    # Using numeric tests
    all(97*c - c*c > 2351 for c in s.encode())
    max((abs(ord(c) - 48.5) for c in "0"+s)) < 1
    all(map(lambda x: (ord(x) ^ 48) < 2, s))

    # Removing all the 0 and 1
    re.sub(r"[01]", "", s) == ""
    len((s).translate(str.maketrans("", "", "01"))) == 0
    len((s).replace("0", "").replace("1", "")) == 0
    "".join(("1".join((s).split("0"))).split("1")) == ""

    # A few more for good measure
    set(s + "01") == set("01")
    not (set(s) - set("01"))
    not any(filter(lambda x: x not in {"0", "1"}, s))
    all(map(lambda x: x in "01", s))
"""

import re
from collections import Counter
from inspect import cleandoc

g = {
    "re": re,
    "Counter": Counter,
}

for test in cleandoc(TESTS).splitlines():
    test = test.partition("#")[0]
    if not test:
        continue
    for ss, expected in [(GOOD, True), (BAD, False)]:
        for s in ss:
            result = eval(test, {"s": s} | g)
            if bool(result) != expected:
                print("OOPS:")
                print(f"   {s = }")
                print(f"   {test}")
                print(f"   {expected = }")

It’s a good thing I did this because a few of the suggestions needed adjusting, especially for dealing with the empty string. But now they all work, and are checked!

BTW, if you prefer Mastodon to BlueSky, the posts are there too: first and second.

Drupal Advent Calendar day 4 - Drupal.org james Wed, 12/04/2024 - 09:00

In case you want to use that inside of neovim using Mason, you will have to remember to have the configuration inside of a settings key. The following is from my setup.

basedpyright = { settings = { basedpyright = { analysis = { diagnosticMode = 'openFilesOnly', typeCheckingMode = 'basic', capabilities = capabilities, useLibraryCodeForTypes = true, diagnosticSeverityOverrides = { autoSearchPaths = true, enableTypeIgnoreComments = false, reportGeneralTypeIssues = 'none', reportArgumentType = 'none', reportUnknownMemberType = 'none', reportAssignmentType = 'none', }, }, }, }, },

Another big release day! Python 3.13.1 and 3.12.8 were regularly scheduled releases, but they do contain a few security fixes. That makes it a nice time to release the security-fix-only versions too, so everything is as secure as we can make it.

Python 3.13.1

Python 3.13’s first maintenance release. My child is all growed up now, I guess! Almost 400 bugfixes, build improvements and documentation changes went in since 3.13.0, making this the very best Python release to date.

https://www.python.org/downloads/release/python-3131/

Python 3.12.8

Python 3.12 might be slowly reaching middle age, but still received over 250 bugfixes, build improvements and documentation changes since 3.12.7.

https://www.python.org/downloads/release/python-3128/
Python 3.11.11

I know it’s probably hard to hear, but this is the second security-only release of Python 3.11. Yes, really! Oh yes, I know, I know, but it’s true! Only 11 commits went in since 3.11.10.

https://www.python.org/downloads/release/python-31111/
Python 3.10.16

Python 3.10 received a total of 14 commits since 3.10.15. Why more than 3.11? Because it needed a little bit of extra attention to keep working with current GitHub practices, I guess.

https://www.python.org/downloads/release/python-31016/
Python 3.9.21

Python 3.9 isn’t quite ready for pasture yet, as it’s set to receive security fixes for at least another 10 months. Very similarly to 3.10, it received 14 commits since 3.9.20.

https://www.python.org/downloads/release/python-3921/
Stay safe and upgrade!

As always, upgrading is highly recommended to all users of affected versions.

Enjoy the new releases
