16.7. Classes as types

As we have seen, in Python all variables have a type. We can use the built-in dir function to examine the capabilities of a variable. We can also use type and dir with the classes that we create.

class PartyAnimal: x = 0 def party(self) : self.x = self.x + 1 print("So far",self.x) an = PartyAnimal() print ("Type", type(an)) print ("Dir ", dir(an)) print ("Type", type(an)) print ("Type", type(an.party))

You can see that using the class keyword, we have created a new type. From the dir output, you can see both the x integer attribute and the party method are available in the object.
