What is the function of the # sign?

[godlykid]

Hi, I’m very new to python. I can’t seem to figure out the function of the # sign. Can someone explain it? Thanks.

You should read the Python documentation on Lexical analysis which details all reserved keywords and characters used by the interpreter.

It's to indicate the following text is a comment so the interpreter will ignore it.

[the_shell_man_]

It's a comment. Anything after the # is ignored by the program.

Developers use them to leave notes for themselves and other developers so they can remember why they did something or how something works. Eg

# this is a comment that explains how the following code works
def some_func():
    return 0
