Re: What is wrong in this example code?

If you are using Python 3 you will need to change xrange to range, but the
error shouldn't be invalid syntax. I remember it should just name name not
found/not defined. So if you are not using Python 3, range and xrange do
still in Python 2 and they have different use case.

So i am really curious how you fixed it. It sounds more like some issue
with space rather, but still glad you solved it somehow.
