Subclass - Arguments From Superclass

I'm a little confused about how arguments are passed between Subclasses and Superclasses in Python. Consider the following class structure:

class Superclass(object):
    def __init__(self, arg1, arg2, arg3):
        #Inilitize some variables
        #Call some methods

class Subclass(Superclass):
    def __init__(self):
        super(Subclass, self).__init__()
        #Call a subclass only method

Where I'm having trouble is understanding how arguments are passed between the Superclass and Subclass. Is it necessary to re-list all the Superclass arguments in the Subclass initializer? Where would new, Subclass only, arguments be specified? When I try to use the code above to instantiate a Subclass, it only expects 1 argument, not the original 4 (including self) I listed.

TypeError: __init__() takes exactly 1 argument (4 given)
