It's not stupid. It's common in the Python world to use * and ** to send
multiple arguments and keyword arguments to a function.
Hopefully these python interpreter examples will help...
>>> def foo(a, b, c, *args):
... print a, b, c, args, type(args)
...
>>> foo(1, 2, 3, 4, 5, 6, 7, 8, 9, 0)
1 2 3 (4, 5, 6, 7, 8, 9, 0) <type 'tuple'>
>>>
>>> my_tuple = (7, 11)
>>> foo(1, 3, 5, *my_tuple)
1 3 5 (7, 11) <type 'tuple'>
>>>
>>> my_list = [5, 7]
>>> foo(1, 3, 5, *my_list)
1 3 5 (5, 7) <type 'tuple'>
>>>
>>> def foo(a, b, c, **kwargs_or_any_old_name):
... print a, b, c, kwargs_or_any_old_name, type(kwargs_or_any_old_name)
...
>>> foo(1, 2, 3, inquisition='Unexpected', beldar_says='Mepps!')
1 2 3 {'inquisition': 'Unexpected', 'beldar_says': 'Mepps!'} <type 'dict'>
>>>
>>> my_dict = {'hello': 'World', 'fizz':'bang'}
>>> foo('x', 'y', 'z', **my_dict)
x y z {'hello': 'World', 'fizz': 'bang'} <type 'dict'>
>>> foo('x', 'y', 'z', my_dict)
Traceback (most recent call last):

As for the login bit... I'm not sure what the solution is but it seems odd
that your form method is 'post' but the error message mentions 'get'.
