How are you running the program?

doubly clicking in a file manager/explorer?
Running from an OS command line?
Importing from the Python >>> prompt?
Or using some kind of IDE? (Which?)

The answer to your question depends a lot on the way you
run the code.

A sample error and your OS and Python version will help too.

Could be. If you import a module then change that module then
reimporting alone is not enough. But if you run the code from the OS 
that shouldn't be an issue. So how do you run the code?
