What is the monkey patching in Python?
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. We use above module (monk) in below code and change behavior of func() at run-time by assigning different value.

Monkey patching is good for testing or mocking out behavior. They can be localized in factory/class decorators/metaclasses where they create a patched new class/object from another object to help with “cross-cutting concerns” in between ALL methods like logging/memoization/caching/database/persistance/unit conversion.
