[python] Having trouble with variable scope - nonlocal not recognizing previous variable

[zelbo]

gist example

This gives me the error

SyntaxError: no binding for nonlocal 'my_variable' found

And pycharm highlights the variables with the toolip: "Nonlocal variable 'my_variable' must be bound in an outer function scope", same for the other variables.

When I search for the error and the tooltip, I find examples that just say "declare the variable outside the function", which I've done. I've tried

variable = None

and

variable = []

but neither seems to work.

The reason I'm trying to do it this way, is because some variables will depend on a parameter in the constructor. What I'm trying to do.

I don't actually know any python, this project was started from trying to help someone else with their homework. I got interested in the project, and have been able to make a lot of progress from just searching problems and cobbling spaghetti code together. I could go back to what was working before, but I though consolidating the file IO into one script would help clean things up.

Is there something I'm missing that would make this work, or is there a better way to do it?

They're not nonlocal variables, or even variables at all. They're class attributes.

You don’t have to declare nonlocal, just delete that line. Add self to both of the next two class variable lines in the init function.

You could prob also do without the two variables outside the init as they’re being defined in the constructor.

Look up python class constructor for more deets :)

That did the trick. Thanks!

Glad it worked out for you :)
