Hi there, I am making a program in python based on a Subway operation. All
descriptions and comments codes are provided in the attached program. I've
been using IDLE to run the program and it seems to work the way I want it
too.

However I have heard from many, that global variables are bad practise in
any programming language, and so I want to basically replace all my global
variables with another variable that does the same thing.

The problem is, some data is entered and then when the data is submitted,
the GUI window terminates and automatically re-opens for another data
entry. I need some sort of variable to store some data while the program
resetts itself.

Sorry is this sounds really broad, and I am happy to clarify and points.
