Hi Glen,

Ah!  Check to see if there's a "sets.py" program somewhere in your current
working directory.  It's very likely that Python is picking that up,
instead of the 'sets' standard library module.

This is one thing that does bite people every so often, because it's all
too easy to accidently write a program uses the same name as a standard
library module.

I wrote a small module a while back as a proposed solution to the issue:


but I don't think it's really being used.

Best of wishes to you!
