Hello, I am learning how to work around moving in pages in tkinter. I asked a question a few days ago about that here: https://python-forum.io/thread-36382.html
I wrote another app using that basis learned there, and this app reads a text file and removes the redundant lines, and returns a list of numbers. The code below returns a list of numbers in PageOne, But as I want to use that list in PageTwo, it changes to a string. I know I have initially introduced variables as strings, but it does not work under other types as well. How I can keep that as a list?
To run this code you can put a few numbers with space separation in a text file and open it using the app.

app.mainloop()I also wondered why the type of list in PageOne is shown with some random numbers? thanks
