Hi All,

How to override method without class?


In a.py file have one method

def abc(self):
     print "Called ABC()"


In b.py i want to override a.py file's abc() method.


I clear about.

1) I am not talking about Class method override.
2) And no any class use in a.py and b.py
3) It is possible to override abc() method without class ?


Thanks in advance,
Harsh Dhaduk

from a import abc

def new_method():


abc = new_method


import a

def new_method():


a.abc = new_method

it's called monkey patching.  You can search the net for other examples, but here is one: http://stackoverflow.com/questions/19545982/monkey-patching-a-class-in-another-module-in-python

method abc is in module a

Hi Harsh,

To override a method you have to understand the object to which that method belongs.

If method abc() belongs to class object 'test'

ie. in .py file it will be like:-

class test (osv.osv):

    _name = 'test'

    def abc():

        return True


If you want to override that function you have to define a class to inherit that object and then define method with same name. Eg:-

IN b.py file

class test(osv.osv):

    _inherit = 'test'

    def abc():

        return True


Here we overrided the method abc()

Thanks a lot!

import a
def ab1(self...):
   something here

a.abc = ab1

Hi Baiju i am not talking about class method override.

Hi Ivan have other examples like monkey patching?

Hi Bole i tried that one but not working.


Thanks for your replay.

Google python monkey patch and you can get a lot of examples.
