Also me when I'm forced to write documentation for a Python function

def delete_first_of_list(the_list: list):

[–] [email protected] 7 points 1 year ago

What if I pass an empty list, or NoneType?

Does this return a new list or modify the original? I would hope it returns a new one but I would know for sure if there was documentation.

I would hope it modifies the original. It's implied in the name. A function that returns all but the first item should be named something like tail or without_first_item.

This is a good way to realise that you don't need a function for that use case.

If they need it often it makes some sense, if it also perform some checks, if the list if empty or None/null.
