Now I understand. Thanks!

I normally don't use from-import, but I have special needs for one
project I'm working on. I process HTML files that contain embedded
Python code, and I define handy variables and functions that can be
used by embedded scripts. I make the definitions in a separate module
to keep code structure clear.
