I have two Python functions, both of which take variable arguments in their function definitions. To give a simple example:
def func1(*args):
for arg in args:
print arg
def func2(*args):
return [2 * arg for arg in args]
I'd like to compose them -- as in func1(func2(3, 4, 5)) -- but I don't want args in func1 to be ([6, 7, 8],), I want it to be (6, 7, 8), as if it was called as func1(6, 7, 8) rather than func1([6, 7, 8]). Normally, I would just use func1(*func2(3, 4, 5)) or have func1 check to see if args[0] was a list. Unfortunately, I can't use the first solution in this particular instance and to apply the second would require doing such a check in many places (there are a lot of functions in the role of func1).
Does anybody have an idea how to do this? I imagine some sort of introspection could be used, but I could be wrong.
