I am very new to python, and I went trhough the railway docs but I stil couldn't understand exactly how to set up the secret variables. What I am trying to do is very simple, I have two api keys, strings, i have loaded them up as service variables, and I put them in quotation marks...is that right? Or they dont need quotations?

I called them KeyA and KeyB, in the variables section

In my python class, I'll want to write

self.keyA = KeyA

self.keyB = KeyB

So exactly how do I write KeyA, and KeyB in my app? I couldn't figure it out from the documentation and Im wasting time trying different things. Thanks
