python - 如何删除字符串中的所有标点符号？（Python）

Question

例如：

asking="hello! what's your name?"

我可以这样做吗？

asking.strip("!'?")

Answer 1

一个非常简单的实现是：

out = "".join(c for c in asking if c not in ('!','.',':'))

并继续添加任何其他类型的标点符号。

一种更有效的方法是

import string
stringIn = "string.with.punctuation!"
out = stringIn.translate(stringIn.maketrans("",""), string.punctuation)

Answer 2

import string

asking = "".join(l for l in asking if l not in string.punctuation)

过滤string.punctuation。

Answer 3

This works, but there might be better solutions.

asking="hello! what's your name?"
asking = ''.join([c for c in asking if c not in ('!', '?')])
print asking

Answer 4

剥离将不起作用。它只删除前导和尾随实例，而不是介于两者之间的所有内容：http: //docs.python.org/2/library/stdtypes.html#str.strip

玩过滤器的乐趣：

import string
asking = "hello! what's your name?"
predicate = lambda x:x not in string.punctuation
filter(predicate, asking)
