Error in wordsteam.py

[kyongsoolee]

Dear, jalajthanaki

These days, I tried to study NLP using your book 'Python Natural Language Processing' in Korea.
I have some problem in Ch3, wordsteam.py.
I tried to solve it through internet searching such as stackoverflow for long time.
(Actually I am a beginner in Python and NLP)
But, I can't solve it. So, finally I think I need your help if you can.
When I run this code, wordsteam.py, I get this below result.
You know how can I fix it?
