Answer 1

Try the string.punctuation

import string
s = "Hello. World, Awesome! Really?"
for c in string.punctuation:
    s = s.replace(c,' PUNCTUATION ')
s
#'Hello PUNCTUATION  World PUNCTUATION  Awesome PUNCTUATION  Really PUNCTUATION '

Or use regex:

import re
s = "Hello. World, Awesome! Really?"
s = re.sub(r'[^\w\s]',' PUNCTUATION ',s)
re.sub(' +', ' ',s)
#'Hello PUNCTUATION World PUNCTUATION Awesome PUNCTUATION Really PUNCTUATION '
