How to remove all the punctuation in a string? (Python)
提问by Wuchun Aaron
For example:
例如：
asking="hello! what's your name?"
Can I just do this?
我可以这样做吗？
asking.strip("!'?")

A really simple implementation is:
一个非常简单的实现是：
out = "".join(c for c in asking if c not in ('!','.',':'))
and keep adding any other types of punctuation.
并继续添加任何其他类型的标点符号。
A more efficient way would be
更有效的方法是
import string
stringIn = "string.with.punctuation!"
out = stringIn.translate(stringIn.maketrans("",""), string.punctuation)
Edit: There is some more discussion on efficiency and other implementations here: Best way to strip punctuation from a string in Python

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

This works, but there might be better solutions.
这有效，但可能有更好的解决方案。
asking="hello! what's your name?"
asking = ''.join([c for c in asking if c not in ('!', '?')])
print asking

Strip won't work. It only removes leading and trailing instances, not everything in between: http://docs.python.org/2/library/stdtypes.html#str.strip
Strip 不起作用。它只删除前导和尾随实例，而不是两者之间的所有内容：http: //docs.python.org/2/library/stdtypes.html#str.strip
Having fun with filter:
享受过滤器的乐趣：
import string
asking = "hello! what's your name?"
predicate = lambda x:x not in string.punctuation
filter(predicate, asking)
