How to get all methods of a python class with given decorator

Question

How to get all methods of a given class A that are decorated with the @decorator2?

class A():
    def method_a(self):
      pass

    @decorator1
    def met         


        

Answer 1

If you do have control over the decorators, you can use decorator classes rather than functions:

class awesome(object):
    def __init__(self, method):
        self._method = method
    def __call__(self, obj, *args, **kwargs):
        return self._method(obj, *args, **kwargs)
    @classmethod
    def methods(cls, subject):
        def g():
            for name in dir(subject):
                method = getattr(subject, name)
                if isinstance(method, awesome):
                    yield name, method
        return {name: method for name,method in g()}

class Robot(object):
   @awesome
   def think(self):
      return 0

   @awesome
   def walk(self):
      return 0

   def irritate(self, other):
      return 0

and if I call awesome.methods(Robot) it returns

{'think': , 'walk': }
