题目: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。 1.程序分析:利用while语句,条件为输入的字符不为’n’. 2.程序源代码:
代码语言:text复制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)
