Finding python editor

[Python666]

I know it's weird, but I'm looking for something to edit python in.
In my school we are not allowed to bring any type of digital device.
Since I'm coding I want to bring something to school to work on my python project.
I talked to my teacher and he said that if I can bring some device that can only edit and run python code I can bring it.
I have seen things like dumbdumb terminal but I don't want to build anything or something like that, I would like to buy it...
Do you know anything like that?

So, if it is school project why do you need to bring device to work on (although not allowed to)? Why not work on school computers?
why not simply use some online ide like repl.it or google colab?

This is not a school project...

This is not a school project...

Then why do you want to work on it in school? Work on it in your free time...

I'm working on this project with someone from my school and many times one of us can't work, and I think we should work in school because we go there everyday
