What could happen if I open a file but forget to use close() on it in Python?

My old programming teacher told me that is bad practice NOT to close files after using open() on them. He mentioned that the reference goes to 0.

Why is closing files important in Python?

I don't know how to answer this. Maybe ask yourself, what happens if you have an important word document, but you don't close it? – taesu Dec 17 '15 at 16:23
