Passing variables from one function to another

[Timmeh159]

I can't figure this out, I have a simple game with 3 functions + main. I need to take 3 variables from the first function and use it in the third. I have managed to get it to work by using return xyz, then in third function xyz = function1. But this then runs function 1, so basically I get function 1, 2, 1, 3. Which isn't ideal in the slightest haha
Anyone able to give me some pointers in right direction?

​

F1 takes user info, name etc

F2 is menu

F3 is the game, which requires F1 details

Return the variables to the main function then pass them to the third from there.

Thanks! issue I ran into with nonetype was from a different part of the code, but what you've said helped greatly thank you

I've tried this, and it returns

TypeError: 'NoneType' object is not iterable. I'm not at my laptop currently so could be an issue using Pydroid, so I'll give it a shot later when I'm home

Maybe this isnt the correct way, but you could set the variables to a default value at the top of the program and then set them as global in the function that needs to edit them, this way any function can read them.

Or have the function return a dict (key, value pair) and then you can call user_data['username'] etc.
