3re.sub('characters_to_pad', r' \1 ', string_of_characters)

5# characters_to_pad

7# Example usage:
8import re
9your_string = 'bla. bla? bla.bla! bla...' # An intelligent sentence
10your_string = re.sub('([.,!()])', r' \1 ', your_string)
11# your_string is updated in place
12print(your_string)
13--> bla . bla? bla . bla ! bla . . .
14# Notice that the '?' didn't have spaces added because it wasn't listed
15# among the characters_to_pad in the above function
