In this example we will show how to count the number of items in a string using Python.
Source Code
#! /usr/bin/env python3
# -*- coding: utf-8 -*-
import string
s = input('Please input a string:n')
letters = 0
space = 0
digit = 0
others = 0
i=0
while i < len(s):
c = s[i]
i += 1
if c.isalpha():
letters += 1
elif c.isspace():
space += 1
elif c.isdigit():
digit += 1
else:
others += 1
print('char = %d,space = %d,digit = %d,others = %d' % (letters,space,digit,others))
Output:
Please input a string:
heho345uaenor fhohto$anf oh*fo @dsof
char = 27,space = 4,digit = 3,others = 3
