[CentralOH] Removing Punctuation

Thanks for this.

I thought I could replace a punctuation mark with a single white space 
by doing this:
S.translate(S.maketrans(" ", " ", string.punctuation))

But that didn't work.  Any ideas how to replace a punctuation mark with 
a single white space?

The reason being, what if there is no space after a punctuation mark or 
three periods were used:
"Mary had a little lamb...little lamb...little lamb! Do you know what 
Mary's problem is?No I do not!"

Then "isNo" ends up being counted as a word and also "lamblittle", so I 
want to prevent this by
replacing a punctuation mark with a singe white space instead of no 
white space.
