I'd like to propose adding argmax and argmin functions to the python list. These functions return the index of a maximum / minimum element of the list. Eg:

a = [1, 4, 2, 3]

print(a.argmax())  # 1

print(a.argmin())  # 0

It's a very popular request (based on stackoverflow https://stackoverflow.com/questions/16945518/finding-the-index-of-the-value-which-is-the-min-or-max-in-python ), and currently there is no elegant way to find it.

What do you think?
