Do python's variable length arguments (*args) expand a generator at function call time?

Question

Consider the following Python code:

def f(*args):
    for a in args:
        pass

foo = [\'foo\', \'bar\', \'baz\']

# Python generator expressions FTW
gen          


        

Answer 1

Why not look and see what gen is in f()? Add print args as the first line. If it's still a generator object, it'll tell you. I would expect the argument unpacking to turn it into a tuple.
