Python - RegEx for splitting text into sentences.

Question

I want to make a list of sentences from a string and then print them out. I don't want to use NLTK to do this. So it needs to split on a period at the end of the sentence and not at decimals or abbreviations or title of a name or if the sentence has a .com This is attempt at regex that doesn't work.

import re

text = """\

Mr. Smith bought cheapsite.com for 1.5 million dollars, i.e. he paid a lot for it. Did he mind? Adam Jones Jr. thinks he didn't. In any case, this isn't true... Well, with a probability of .9 it isn't.

"""

sentences = re.split(r' *[\.\?!][\'"\)\]]* *', text)

for stuff in sentences:

        print(stuff)    

Example output of what it should look like

Mr. Smith bought cheapsite.com for 1.5 million dollars, i.e. he paid a lot for it. 

Did he mind?

Adam Jones Jr. thinks he didn't.

In any case, this isn't true...

Well, with a probability of .9 it isn't.

Answer 1

You need to use the following regex.

(?<!\w\.\w.)(?<![A-Z][a-z]\.)(?<=\.|\?)\s
