import re

str1 = input ("Enter the sentence less than 50 characters: ")

pattern = '[a-zA-Z]'

count=0

i=0

while (i<=len (str1) - 1):

result = re. match (pattern, str1)

if (result):

count+=1

else:

continue

i+=1

print ("String Length:", count)

Explanation:

I have used here the re library that is meant for the regular expressions in Python.
