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

I can propose a few versions.

You can replace each space with an empty string and calculate the length:

len(mystr.replace(" ", ""))

You can calculate the length of the whole string and subtract the number of spaces:

len(mystr) - mystr.count(' ')

Or you can sum the lengths of all substrings after splitting the string with spaces:

sum(map(len, mystr.split(' ')))
