Thanks, that did it.

I would be interested in a bit more explanation though. In the "real"
application, "i" were instances, not numbers (if that matters). Why would
the 'i' in the previously created lambda commands "shift" to follow the
outside value of i?

I thought I understood Python's scoping. ;-)
