Python是否针对特殊字符和/或标点内置字符串验证？

Question

Python has str.isalnum() , str.isdigit() , str.isupper() , str.islower() , str.isalpha() , but does it have any built-in string validation checking for special characters or punctuation? (ie !@#$%^&*().,;'": ect)

Answer 1

The standard string module provides string.punctuation , which contains punctuation characters. You can test for membership in that:

def ispunct(ch):
    return ch in string.punctuation

import string
>>> print string.punctuation
!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~
