python subclass list(reflection)

Sometimes we need get list of subclass of a class. It is very simple in python.

 
class MyClass(object): pass

class SubClassA(MyClass): pass
class SubClassB(MyClass): pass
class SubClassC(MyClass): pass

print([cls.__name__ for cls in vars()['MyClass'].__subclasses__()])

Output:

['SubClassA', 'SubClassB', 'SubClassC']
