it helps if you include the code you were running, instead of some
approximation of it.
File "test", line 10
if passwd = 'godwin': print "You are a valid user"

super() only works for new-style classes.
the second argument problem is because do_ methods are called with
a second argument:
>>> import cmd
>>> help(cmd)
Help on module cmd:
...
3. A command `foo' is dispatched to a method 'do_foo()'; the do_ method
is passed a single argument consisting of the remainder of the line.
...
(if you type "login", you get an empty string. if you type "login foo", you get
the string "foo". etc).
