Any reason for that specifically?
Is there any particular reason for the number of arguments to be part of the function signature? I totally get the notion of declaring how many arguments a function takes, but why does it have to be in the function signature? Data types are just as much a part of that signature as argument count is. You could argue that the function's return type isn't part of that, but that's about it. > If there is a pep for it, people will use it, so the fact that > it is optional is irrelevant... Function annotations were introduced in 2006 (Python 3.0) with PEP 3107: https://www.python.org/dev/peps/pep-3107/ They were optional then, they are still optional now. Have you been overrun with them for the past decade? If not, why do you expect now to be? ChrisA -- https://mail.python.org/mailman/listinfo/python-list
