try:
users[user].append("%s : %s" % (data1, data2))
except KeyError:
users[user] = ["%s : %s" % (data1, data
ne. If you don't have the needed code yet,
you need to put a 'pass' here :
if some_condition:
pass
else:
pass
This will of course do nothing else than useless tests, but it will at
least satisfy the language's rules.

problem with z to handle,
No. AFAICT, the name error could be with x and/or y and/or z.
so where is the gain of using
lambda or the mapping?

I think it would be nice to have, but I
can't imagine it to be really very helpful.
I once had the same feeling about first class functions, higher-order
functions, lambdas, list comprehension, __call__ special method,
descriptors, metaclasses, and a whole lot of other constructs
