I am looking a shorter way to do the above in the case:
def g(*arg):
return arg
def f(*arg):
return g(arg)
How can g know if it is called directly with (('foo', 'bar'),) or via f
with ('foo', 'bar'). I coud write in f: return g(arg[0], arg[1]) if I
know the number of arguments, but what if I don't know that in design time?
