After lots and lots of extended matches, index error occurred. It has occurred in getLocations function. Can you please help? Have shared an error log.
Extending match backwards with words: adv adv
Extending match backwards with words: car car

I just wrapped that code in a try/except that should fix that, I hope. Could you pull the latest version (from here on GitHub), and try again, and let me know if it works?
Yup it handled error there, but it goes into an infinite loop in extend_matches() function. Keeps printing same set of "Extending match backwards with words: xyz". And after lot of time IndexError at:
IndexError

Please can you help me with this?
Sure. Could you give me a copy of the text pairs you're using that cause the error? I'm having difficulty reproducing the error myself, using my test texts.

Have sent the strings to reproduce error. Let me know if it doesn't produce error.
I have mailed it at jon.reeve@gmail.com, is it okay?
The issue was due to identical strings. When both strings are 100% identical it raises an error. Handled it using try except again. Also the sample which i mailed you , i later found that they were not correct.
Anyways, Great work, coding style and its depth. Loved it!!!.
Thank you so much.
Ok, glad it worked out! Let me know if you encounter any other errors. Also, I'm going to use this program a lot myself in the upcoming weeks, so I'll probably release a new version or two then.
