That's a basic assignment example. It's not a direct manipulation of
globals(), like the solution given by Jan, which you seem to fee

Well, you're using a namespace, which namespaces its in would depend
on the scope in which that assignment occurred. And there's not really
a global namespace, only modu

That depends on whether you are doing x = className() inside a function
(or class), or in the top level of the
Thanks for pointing it out Steve. The blog post doesn't explain it
very well. I understand the risk of exec or eval(input). but what are
the risks of globalnamespace use and what are the benefits?

You're unnecessarily tying your code to the implementation.

Thanks Jan,
You read my mind. That is exactly what I needed.
Thanks for showing the product function from itertools as well. It
seems easier to grasp than the nested loops, I had been using.
I noticed chopin.edu.pl. Are you a musician?

I have a class of let's say empty bottle which can have a mix of two
items. I want to create let's say 30 of these objects which will have
names based on the 2 attributes (apple juice, beer, grape juice, beer,
