方法一：
def Character(Str): letters,digits,spaces,others = 0,0,0,0 for s in Str: if 'a'<=s<='z' or 'A'<=s<='Z': letters += 1 elif '0'<=s<='9': digits += 1 elif s==' ': spaces += 1 else: others += 1 return letters,digits,spaces,others print(Character('I am Hann Yang, my email is [hann@126.com].'))
方法二：与string库中的几个常量比较
def Character(Str): import string letters,digits,spaces,others = 0,0,0,0 for s in Str: if s in string.ascii_letters: letters += 1 elif s in string.digits: digits += 1 elif s in string.whitespace: #whitespaqce除了空格还包括'\t\n\r\x0b\x0c' spaces += 1 else: others += 1 return letters,digits,spaces,others print(Character('I am Hann Yang, my email is [hann@126.com].'))
