How to remove all the punctuation in a string? (Python) [duplicate]

Answer 1

A really simple implementation is:

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

and keep adding any other types of punctuation.

A more efficient way would be

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

Answer 2

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

Having fun with filter:

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

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

import string

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

filter with string.punctuation.
