Is it possible to pass member variable names as arguments?

Question

I was wondering if such a construction was possible in Python :

class A():
    def method1(self):
        print ('method 1')

    def method2(self):
        print ('method 2')


a = A()
call_method(a, 'method1')
call_method(a, 'method2')

Expected result : method 1 method 2

How to define call_method ?

Thanks in advance
