str.translate can be used instead of re.

# Compute only once somewhere
punctuation_removal_table = str.maketrans({c: None for c in string.punctuation})


    no_interpunction = sentence.translate(punctuation_removal_table)

Unfortunately you'll remove all the apostrophes and dashes, both
of which could be considered parts of words.
