Using len for text but discarding spaces in the count

Question

So, I am trying to create a program which counts the number of characters in a string which the user inputs, but I want to discard any spaces that the user enters.

Answer 1

Why can't you just do:

>>> mystr = input("Please enter in a full name: ")
Please enter in a full name: iCodez wrote this
>>> len(mystr.replace(" ", ""))
15
>>> len(mystr)
17
>>>

This gets the length of the string minus the spaces.
