您也可以这样做：

import string
' '.join(word.strip(string.punctuation) for word in 'text'.split())

我喜欢使用这样的函数：

def scrub(abc):
    while abc[-1] is in list(string.punctuation):
        abc=abc[:-1]
    while abc[0] is in list(string.punctuation):
        abc=abc[1:]
    return abc

为了方便使用，我总结了Python 2和Python 3中从字符串中删除标点符号的注意事项。有关详细说明，请参阅其他答案。

Python 2

import string

s = "string. With. Punctuation?"
table = string.maketrans("","")
new_s = s.translate(table, string.punctuation)      # Output: string without punctuation

Python 3

import string

s = "string. With. Punctuation?"
table = str.maketrans(dict.fromkeys(string.punctuation))  # OR {key: None for key in string.punctuation}
new_s = s.translate(table)                          # Output: string without punctuation

这个问题没有太多细节，所以我采取的方法是用最简单的解释来解决这个问题：去掉标点符号。

请注意，所提供的解决方案不考虑收缩词（例如，you are）或连字符词（例如肛门保留）。。。这是关于它们是否应该被视为标点符号的争论。。。也不能解释非英语字符集或类似的东西。。。因为问题中没有提到这些细节。有人认为空格是标点符号，这在技术上是正确的。。。但对我来说，这在当前问题的背景下毫无意义。

# using lambda
''.join(filter(lambda c: c not in string.punctuation, s))

# using list comprehension
''.join('' if c in string.punctuation else c for c in s)

这是我写的一个函数。它不是很有效，但很简单，您可以添加或删除任何您想要的标点符号：

def stripPunc(wordList):
    """Strips punctuation from list of words"""
    puncList = [".",";",":","!","?","/","\\",",","#","@","$","&",")","(","\""]
    for punc in puncList:
        for word in wordList:
            wordList=[word.replace(punc,'') for word in wordList]
    return wordList

显然，我无法对所选答案进行编辑，所以这里有一个适用于Python3的更新。在进行非平凡转换时，转换方法仍然是最有效的选择。
