输入一行字符,分别统计出其中英文字母、空格、数字和其它字符的个数。
#!/usr/bin/python
# -*- coding: UTF-8 -*-
import string
s = raw_input('input a string:\n')
letters = 0
space = 0
digit = 0
others = 0
for c in s:
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,othe
Python 判断字符属于数字、字母、空格的方法:
字符 c.isalpha()
空格 c.isspace()
数字 c.isdigit()
