s = "Bob hit a ball!, the hit BALL flew far after it was hit."

I need to get rid of the following characters from s

!?',;.

How to achieve this with re.sub?

re.sub(r"!|\?|'|,|;|."," ",s) #doesn't work. And replaces all characters with space

Can someone tell me what's wrong with this?

The problem is that . matches all characters, not the literal '.'. You want to escape that also, \..

But a better way would be to not use the OR operator |, but simply use a character group instead:

re.sub(r"[!?',;.]", ' ', s)
