I was wondering if you might want to write a small function so that
you can remove all punctuation symbols from each line in one fell
swoop? Something like (in pseudocode):
Iterate over string.punctuation.
If a punctuation symbol is in your string: Replace that symbol with
an empty string.
=>>> maybe something like
import re
no_interpunction = re.sub("[%s]" % re.escape(string.punctuation), '', sentence)
