You'll need to post the whole code of your program. That function
works fine for me. (Though it's somewhat unPythonic code, and in any
case already exists in the standard library.) Tip: Look at the full
traceback from the error. Chances are you'll find the cause of the
error on one of the lines near the end of the trace.
