This is almost surely a problem in your environment, and not a bug in python. This bug tracker is for reporting bugs in python.

I suggest you look for help elsewhere, such as the python-list mailing list (https://mail.python.org/mailman/listinfo/python-list) or the python-tutor mailing list (https://mail.python.org/mailman/listinfo/tutor).

But even if this is a bug in python, you've given us no information to use to help you. Given what you've told us, how would you expect us to respond? You'll need to provide a lot more information before we can even begin to guess what problem you're having.
