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.
Nice, I did not think of str.translate. It appears to be the fastest (and most
readable) method, though a compiled regex is also pretty fast:
