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

Maybe, if the decorators are not too complex (but I don't know if there is a less hacky way).

def decorator1(f):
    def new_f():
        print "Entering decorator1", f.__name__
        f()
    new_f.__name__ = f.__name__
    return new_f

def decorator2(f):
    def new_f():
        print "Entering decorator2", f.__name__
        f()
    new_f.__name__ = f.__name__
    return new_f


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

    @decorator1
    def method_b(self, b):
      pass

    @decorator2
    def method_c(self, t=5):
      pass

print A.method_a.im_func.func_code.co_firstlineno
print A.method_b.im_func.func_code.co_firstlineno
print A.method_c.im_func.func_code.co_firstlineno
