Constructors can have additional parameters
Inheritace
The new class (child) has all the capabilities of the old class (parent) - and then some more -> the ability to take a class and extend it to make a new class

points = 0
def touchdown(self):
self.points = self.points + 7
self.party()
print self.name,"points",self.points
