Monkey patching :

A dynamic modification of class module patch at run time in python this called monkey patching term.

example:

# m.py 
class MyClass:

def f(mindstick):

print "f()"

We can then run the monkey-patch testing like this:

import m 
def monkey_f(mindstick):

print "monkey_f()"

 

m.MyClass.f = monkey_f

obj = m.MyClass()

obj.f()

The output will be as below:

monkey_f()

in above example some changes in the behavior of f() in My Class using the function. monkey_f(), outside of the module m.
