Title Body

I have a super class with a method that calls other methods that are only defined in its sub classes. That's why, when I create an instance of my super class and call its method, it cannot find the method and raises an error. Here is an example: class SuperClass(object): def method_one(self): value = self.subclass_method() print value class SubClassOne(SuperClass): def subclass_method(self): return 'subclass 1' class SubClassTwo(SuperClass): def subclass_method(self): return 'nubclass 2' s1 = SubClassOne() s1.method_one() s2 = SubClassTwo() s2.method_one() c = SuperClass() c.method_one() # Results: # subclass 1 # nubclass 2 # Traceback (most recent call last): # File "abst.py", line 28, in <module> # c.method_one() # File "abst.py", line 4, in method_one # value = self.subclass_method() # AttributeError: 'SuperClass' object has no attribute 'subclass_method' I was thinking about changing the __init__ of super class and verify the type of object, when a new instance is created. If the object belongs to super class raise an error. However, I'm not too sure if it's the Pythonic way of doing it. Any recommendations?
