Since no one else mentioend it: this is only iteration in languages
which mandate tail recursion elimination. Languages that don't do that
are free to do the recursion, which will eventually run you out of
stack. Python is in the latter category, and that's what you ran into.

Thinking about iteration this way is elegant - but it doesn't work
everywhere. Sorry.
