Python allows programmers to pass additional arguments to functions via comments. Now armed with this knowledge head out and spread it to all code bases.

Feel free to use the code I wrote in your projects.

Link to the source code: https://github.com/raldone01/python_lessons_py/blob/main/lesson_0_comments.ipynb

Image transcription:

from lib import add

# Go ahead and change the comments.
# See how python uses them as arguments.

result = add()  # 1 2
print(result)
result = add()  # 3 4
print(result)
result = add()  # 3 4 5 20
print(result)

Output:

    I hate this shit being routinely used in PHP. Symfony uses those functional comments for routing, essentially scanning every controller file as text on every visit, to gather the url patterns above functions. Laravel uses Reflection, which is functionally the same thing, to provide arguments to controller functions. Also, kind of related, the project I’m working now has few functions that use backtrace to return different results based on where they are called from. It is indeed very cursed and I’m ripping out any usages of them whenever I see one.

    I assume the people freaking out about how dumb python is didn’t bother to read the code and have never coded in python in their life, because the behavior here is totally reasonable. Python doesn’t parse comments normally, which is what you’d expect, but if you tell it to read the raw source code and then parse the raw source code for the comments specifically, of course it does.

    You would never, ever accidentally do this.

    …you’d also never, ever do it on purpose.

      Yup, the function actually goes and finds the code that calls it and parses the comment.

      Disgusting.

    What? There is no lib module.

    $ python3.13 -c 'import lib'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import lib
ModuleNotFoundError: No module named 'lib'
$

      OP wrote this add() function and has provided their own lib module in the source code.

        Oh, so it’s not Python that’s cursed.

        One of Python’s design philosophies is—or at least was—“we are all consenting adults here.” If you really want to turn Python into Brainfuck, the interpreter isn’t going to stop you.
