Python 练习范例 17
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
分析
利用 while 语句,条件为输入的字符不为 '\n'
#!/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,others)
以上 Python 代码输出结果如下
input a string: 简单教程 char = 6,space = 0,digit = 0,others = 0
