It’s an awful piece of garbage that pretends to be an IDE.

No, they won’t. They will be replaced by a much worse and less
friendly IDE. Please don’t bother installing IDLE and use the normal
`python3` shell, ipython or bpython.

The correct fix is to exit() from the python3 shell and start it again.
Alternatively, add some main code at the end of your file and use
`python3 hlibert.py`:

if __name__ == '__main__':
