检测某些用户输入中的标点符号的最佳方法是什么？我希望达到 GCSE 水平，请不要做太复杂的事情

Question

Sentence = input("Type a sentence")

Loop = True

While loop = True:
    If # something to detect punctuati#:               
        Loop = True
    Else:
        Loop = False

Answer 1

如果您想要简单的东西，可以punctuation从字符串导入，然后检查字符串是否包含标点符号字符。

from string import punctuation

my_text = 'What?'

>>> any(p in my_text for p in punctuation)
True

例子

while True: 
    s = raw_input('type a sentence without punctuation: ')  # Python 2
    if not any(p in s for p in punctuation):
        break
