Python append function as dot notation

Question

def do_something(obj, func):
    obj.func()

My question is how do I call func on obj? func is a function of obj. Is this even possible?

Answer 1

If func is an actual function of obj you can simply call it:

func()

An example:

class Klass(object):
    def say_hi(self):
        print 'hi from', self

func = Klass().say_hi
func()   # hi from <__main__.Klass object at 0x024B4D70>

Otherwise if func is the name of the function (a string) then this will get it and call it:

getattr(obj, func)()
