I am new to python. I have a few questions coming from an armature!

It's mostly about idioms. Comprehensions belong to Python's core idioms,
lambdas don't.
In Scheme, I think it's the other way around. Too many Scheme
programmers are infatuated with Scheme's powerful macros and bury
Scheme's idiomatic, functional core under truckloads of foreign patterns
-- just because they can.
So use lambda in Scheme as much as you can. Avoid lambda in Python as
much as you can.
