Hi,
I try to get a set of lambda functions that allows me executing each
function code exactly once. Therefore, I would like to modify the set
function to compare the func_code properties (or the lambda
functions to use this property for comparison).
(The reason is that the real function list

I V:
You might instead want to
wrap the lambdas in an object that will do the comparison you want:
This looks very nice, I haven't tried it yet, but if it works well
then it may deserve to be stored in the cookbook, or better, it may
become the built-in behavior of hashing functions.
Bye,
This may have some bugs left, but it looks a bit better:
from inspect import getargspec
class HashableFunction(object):
Class that can be used to wrap functions, to allow their
hashing,
for example to create a set of unique functions.
func_strings = ['x', 'x+1', 'x+2', 'x']

Manually creating the lambdas and appending them to a list works as
expected, naturally; I don't see a good reason why it wouldn't work
with a loop. Am I missing something?
Yes, you

I think it worth the reminder that Python has lambda *expressions* that
result in function objects
