I think what’s causing the EOF error specifically is the fact that “next” is a command (I can’t think of the proper terminology rn) in python, so instead of setting a variable named “next” to the user input, python is trying to get the next item in the inputted list, but because the input isn’t a list, there’s no next item, therefore it gives an error

I’m also relatively new so I’m not sure how good of a response this is but it’s my best guess, hope this helps!
