How to count the number of letters in a string without the spaces?

Question

This is my solution resulting in an error. Returns 0

PS: I\'d still love a fix to my code :)

from collections import Counter
import          


        

Answer 1

string=str(input("Enter any sentence: "))
s=string.split()
a=0
b=0

for i in s:
    a=len(i)
    b=a+b

print(b)

It works perfectly without counting spaces of a string
