Error in code using super

I am unsure why the code below results in an error. I am just creating a Sub-Class Option to the base class Security and try to use super.get_description() in the get_description() function which results in an Error.

class Security(object):
    def __init__(self, name, BriefDesc):
        self.name = name
        self.BriefDesc = BriefDesc

    def __str__(self):
        return self.name + ' ' + self.BriefDesc + ': ' + self.get_description()

    def get_description(self):
        return 'no detailed description.'

class Option(Security):
    def __init__(self):
        Security.__init__(self, 'Option', '(Derivative Security)')

    def get_description(self):
        return super.get_description() # Error here when print is executed. I am unsure why

    def study_security(security):
        print security   

print study_security(Option()) # Results in an error

You need to call super and pass in the correct arguments1:

return super(Option, self).get_description()

Here is a link to the documentation for super.

1This last part is only necessary in Python 2.x though. In Python 3.x, you can just do:

return super().get_description()
