Python add to a function dynamically

Question

how do i add code to an existing function, either before or after?

for example, i have a class:

 class A(object):
     def test(self):
         print         


        

Answer 1

If your class A inherits from object, you could do something like:

def test2():
    print "test"

class A(object):
    def test(self):
        setattr(self, "test2", test2)
        print self.test2
        self.test2()

def main():
    a = A()
    a.test()

if __name__ == '__main__':
    main()

This code has no interest and you can't use self in your new method you added. I just found this code fun, but I will never use this. I don't like to dynamicaly change the object itself.

It's the fastest way, and more understandable.
