In Python, the term monkey patch refers to dynamic (or run-time) modifications of a class or module. In Python, we can actually change the behavior of code at run-time.
# monk.pyclass A: def func(self): print ("func() is being called") |
We use above module (monk) in below code and change behavior of func() at run-time by assigning different value.
import monkdef monkey_f(self): print ("monkey_f() is being called") # replacing address of "func" with "monkey_f"monk.A.func = monkey_fobj = monk.A() # calling function "func" whose address got replaced# with function "monkey_f()"obj.func() |
Examples:
Output :monkey_f() is being called
