They Said THIS Was Impossible In Python

They said this was impossible in Python #python #code #shorts

This is the definition of just because you can doesn't mean you should

[coolcodingcat]

You could also use checking the types with `if type(arg) …` checks and make it do different things based on the type, but this seems like a cleaner solution that mimics strongly typed languages.

I know about partial functions in Python but function overloading is so cool.

[ravikatiyar]

Looks painful, I would rather make peace with “python doesn’t support function overloading”

[stefanoctaviansterea]

I think this simulates real function overloading using reflection. Decorators are really powerful tools that can hide a thon of stuff behind some concise yet vague syntax.

[xzex]

we can overload functions with three methods (with if /match case )
2.In this method we can achieve the function overloading by user-defined function using the “None”
Keyword as the default parameter.
3. using multipledispatch
from multipledispatch import dispatch

and ofcource your way( the three )

[pradyumnachakraborty]

Ever heard of the factory design pattern?

[apmcd]

There is a Multiple Dispatch, too, but that has to be installed with pip, conda, etc

[xzex]

why don't you ( for this example) use (if/match case) of is_instance(object, arg) and with less lines of code define what the function do, due to the input type ??

[rnseby]

I already know where I'm going to use this. I've been using isinstance, but this looks so much cleaner. I can finally tackle that big function and break it down to nice small chunks.

Ooo, rozprawka bardzo dla mnie, , ,amerykanisty'' (nawet nie znałem tego słowa!). Dziękuję!

[cycrothelargeplanet]

I'd rather use if/elif/else than this

[callbettersaul]

def func(arg):
if type(arg) == str:
do somthing
if type(arg) in [float, int]:
do something else

[developer_anonymous]

I thought you needed to use typing's overload decorator 😅

[adventuresofavalon]

I thought this was a unique feature of Object Oriented Programming

[AWriterWandering]

Honestly seems way too cumbersome. Especially since you can use named arguments with default values.

[kpbendeguz]

I can't think of any practical use of this.

[Saheryk]

if type(arg) is str:
doThis
if type(arg) is int:
doThat

[HarmSalomons]

isn't is easier to use **kwargs and testing the name and type of a parameter?

[magicalbologna]

Wait whoah I had no idea this applied to functions and not just methods
