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:

    yeah frankly this post is borderline misinformation, they specifically import a library to read comments as arguments, it’s like redefining keywords in C and complaining about C being dumb

        Yeah. ‘lib’ isn’t a standard Python library, it’s the name of the abomination that this person created. Since python has quite a bit of useful introspection, they can do something like:

        • get the stack
        • find the exact call to abomination.add()
        • reparse the text of that line, turn the text of the comment into actual numbers, and add them

        Now, I don’t know if python keeps the comments around, so it may involve getting the filename and line number, reading the file, and manually extracting the comment text from that line.

          It’s not even actually called lib. The line just straight up isn’t in the image “transcribed”, and it’s from arglib import comment_arguments in the original code.

          Yeah, I gave this one a downvote.
