Thanks. My solution became:

 >>> def flattern(arg):
...     result = []
...     for item in arg:
...         if isinstance(item, (list, tuple)):
...             result.extend(flattern(item))
...         else:
...             result.append(item)
...     return tuple(result)
...
 >>> def g(*arg):
...     arg = flattern(arg)
...     return arg
...
 >>> def f(*arg):
...     return g(arg)
...
 >>> f('foo', 'bar')
('foo', 'bar')
