Hi, I'm building this project and I'm stuck on whether to use classes or functions. I mean, I know classes are like blueprints for objects and all that, but sometimes it feels like functions would do the job just fine. When do I know if I'm overcomplicating things with classes?

What's the difference between a decorator and a context manager in Python? Provide an example use case for each.

Removing coderunner and leaving just regular Python extension should be sufficient.

For VScode Python
I have code-runner but it doesn't run the inputs in the terminal

If binding has nothing to do with it, why does f() return 20 instead of 10? The closure is clearly bound to the name i, not its value at definition time

Python

17 July 2025 12:20

i = 10
def f():
return i # Will use CURRENT value of i (late binding)

Python

it might help you to explicitly initialize "res" as an instance of Config class

Python

17 July 2025 12:16

And for this also


# What does this output? Why?

actions = [lambda x: x + i for i in range(3)]
print([a(10) for a in actions]) # Hint: Same issue!




Late binding strikes again ☹️😓😓

looks like you need an offtopic group, please continue this conversation at @pythonofftopic

"Honestly, decorators and context managers are kinda like two different tools in your Python toolbox. Decorators are super useful for adding some extra functionality to a function without messing with the code inside it. Like, you can use a decorator to log when a function is called or to check if someone's logged in before letting them use it.

Context managers, though, are more about making sure things get cleaned up properly. You know, like when you're working with files or database connections. You want to make sure you close them when you're done, or it can cause problems. Context managers help you do that reliably.

I'm pretty sure that's right... lol"

Adding the word Python to your off-topic question doesn't magically turn it to a Python related question, so please delete your message here and move to the @PythonOfftopic group and ask there.

It will use the value of i that i has at the the time of the function being executed. Which is the same that happens if you define functions in a loop that uses i. At the end of the loop, i has the last value. When you call your functions, it prints that value.

Python

17 July 2025 12:21

i = 20
print(f()) # Output: 20

Binding absolutely has everything to do with it—but maybe we mean different things by 'binding'. Are you saying closures don’t involve variable binding at all, or that late binding isn’t the root cause here?

Python

17 July 2025 12:16

the same reason
binding has nothing to do with it

Python

17 July 2025 12:12

closures work this way: they use ACTUAL variable value
all three functions use the same variable
this variable stores only one value.
