Best way to strip punctuation from a string

Question

It seems like there should be a simpler way than:

import string
s = \"string. With. Punctuation?\" # Sample string 
out = s.translate(string.maketrans(\"\",\         


        

Answer 1

myString.translate(None, string.punctuation)

Answer 2

Regular expressions are simple enough, if you know them.

import re
s = "string. With. Punctuation?"
s = re.sub(r'[^\w\s]','',s)

Answer 3

>>> s = "string. With. Punctuation?"
>>> s = re.sub(r'[^\w\s]','',s)
>>> re.split(r'\s*', s)


['string', 'With', 'Punctuation']

Answer 4

A one-liner might be helpful in not very strict cases:

''.join([c for c in s if c.isalnum() or c.isspace()])

Answer 5

Considering unicode. Code checked in python3.

from unicodedata import category
text = 'hi, how are you?'
text_without_punc = ''.join(ch for ch in text if not category(ch).startswith('P'))

Answer 6

This might not be the best solution however this is how I did it.

import string
f = lambda x: ''.join([i for i in x if i not in string.punctuation])
