THIS Feels Incredibly WRONG In Python, They Call It: "Monkey Patching"

Yes, you read it correctly. In this video I will be showing you a concept which they call "monkey patching" in Python. As crazy as it sounds, it does have some interesting usages!

This is possible because function are objects in python. In C the closest thing are function pointers (which is what does python under the hood).

[@AWriterWandering]

It occurs to me that this is the closest thing Python has to externally defined methods in languages like C++.

I really thought monkey patching might be the practice of senior developers throwing excrement over the code written by junior developers...

[@zapp7746]

Zapp here, and I was the first person here, remember me

[@Kommentierer]

Feels like shooting with pointers like a C-guy.

Mocking is better. Use dependency injection and a strategy pattern.

[@mage1over137]

So because in python modules are objects, and all you need for a module is a file, I have this way of building simple utility scripts that evolve as the complexity grows. I use this technique to create sub class without making a class. At some point everything gets refractored into a class. But it's really a nice way to build a project from scratch.

Very informative! 😄👍

i just implemented monkey patching without realizing it had a name. SUPER useful!

[@linux2420]

This is terrifying and i love it

[@rje4242]

in python you can effortlessly redefine any function, even built in ones, which is a terrific way to trip yourself up:

I really don't care how it feels in Python, as long as it's useful 👌.

Where I work, we often have to modify production code, and and restart the production process, which is what we call monkey patching. This is going around the usual process of modifying in a development environment, test, build and release to production (install a proper upgrade).

[@lukerichards22]

I did something like this once when I wanted to debug by reading all of the print statements on a script that outputted a LOT of print statements. I just changed the print function to one that wrote the repr string to a file instead. Did the job.

[@zangdaarrmortpartout]

When testing you should use mocks, it's basically monkey patching with more functionality, less bloat code, and also cleaner

[@nordgaren2358]

You know you can use this to add to the function by saving the function in a variable, first, and then calling it inside the patched function? It looks a bit weird, but that's kind useful. Allows you to either change the imput before calling the original function, or change the output after calling it!

Hey Indently I have a problem, when I was making my discord bot on python I finished but I didnt get the same thing as you I got "process finished with exit code 0" what do I do?

Thanks for the video
