I have an issue with my code, from this


def create_functions():
functions = []
for i in range(3):
def f():
return i
functions.append(f)
return functions

f1, f2, f3 = create_functions()
print(f1(), f2(), f3()) # I Expected: 0 1 2, Actual: 3 3 3


Why does i=iwork? (Default args are evaluated at function creation.)

How does thiss relate to lambda in loops? Same issue

Have you done some searches on google regarding that? It is a basic conceot and should be there tons of articles and materials to learn

Python

So you didn't look at it. The official tutorial is very easy to follow, give it a chance

Python

16 July 2025 10:38

The official documentation has the best tutorial you can use to start

Please provide a full explanation including all the details that you consider relevant. Your statement is too broad and there is no clear way to answer you, you have to explain:

- what you're doing
- what you're expecting
- what you're using
- where you're running the script
- what Python version you're using
- what packages and their versions you're using
- and the most important thing: show the code YOU wrote (read rule 5️⃣ for that)

and more details, that way your chances to get help will increase.

Hey , I have modified a function but it’s working for the future inputs but not working for the existing ones which one is in my db

If you define your base class as a protocol, then every class that implements that protocol should include all the functions (methods) defined at protocol

In this usecase, ABS is maybe a better choice as it gives you apstract methods that need to be defined by user supplied class, and a "general" - all instances methods (like run or get_name)

In your usecase, inheritance is better choice (i think)

Yea yea, surprised something this nit picky was thought of lol

Python

16 July 2025 06:49

As @razorblade23 pointed thats a good solution but, also consider to sue a protocol instead of a base class to do duck typing

Python

So you don't want to import it?

That's normal to import something "just for types" and it's usually no need for tricks with if TYPE_CHECKING. It's meant for solving real problems, not creating noise.

Python

16 July 2025 07:43

I somewhat understand this. Seems crazy though you can pick and choose like that but i guess it makes no difference at runtime

So my base consumer has an abstract method process the user needs to implement so they send the data wherever they want and 2 other normal methods run and get_name

If i make it so the protocol is defined by those methods and attributes, or i guess even just process and run since that's what i expect in my code to be implemented, the user can build whatever class they want

Python

Sorry now you lost me

Python

16 July 2025 06:49

And this also avoids issues with imports in some cases

Python

16 July 2025 06:48

You mean something like this?

from typing import TYPE_CHECKING

if TYPE_CHECKING:
    from package.things import Thing

def func(it: "Thing") -> None:
    ...

Python

Well I'm only importing it for the type hinting. I don't actually use it in the code at all

async def run_pipeline(self, consumers:List[BaseConsumer]):

Just seems like a weird design choice since you can't really depend on imports to actually be used in the module then. Something could be imported just for types
