You can do this with a list comprehension:
bob(*[possible[k] for k in bob2.func_code.co_varnames])
The LC creates a list of arg values in the same order as the var names
for the function. Putting a * before the list when you call bob()
turns that list into it's arguments.
Alternativly (and this may not be useful) you can call a function with
a dictionary of arguments:
def bob(**kwargs):
print kwargs
possible = {'a' : 10, 'b':5, 'c':-3}
>>> bob(**possible)
{'a': 10, 'c': -3, 'b': 5}
>>>
