How to get variable from a class to another Tkinter window

The goal is to pass the variable string1 from class Display to be used in another Tkinter window. So when the button named Next [in class Display load function] is clicked, it would open a new Tkinter window. And in the new window, the variable string1 from class Display needs to be retrieved for further action. May i know should i create another class Display2, or should i just add a method in the class Display? Just not sure if it's how it's done. Any pointer would be appreciated.

Currently the string variable can be passed as reference from class Display to the class Action_Data. But how can it be passed to another Tkinter window? Many thanks

from tkinter import *  import tkinter as tk    #Application window  root = tk.Tk()    #Display Class  class Display (tk.Frame):      def __init__(self, master, display_data):          tk.Frame.__init__(self,master)          self.master = master          master.title("Display")                    #passing data as reference          self.display= display_data          #button          self.load_button = tk.Button(self, text="Load", command=self.load)          self.load_button.pack()                         def load(self):             #get value      pathlabel2.config(text=files[0])      string1=files[0]      self.display.action1(string1)        self.acition_button = tk.Button(self, text="Next",       command=self.new_window)      self.acition_button.pack()  

Action_Data Class which its variable path1 for clean_inpsection method need the value from display class's load method variable [string1]

#Action_Data Class            class Action_Data(tk.Frame):          def __init__(self, master):              tk.Frame.__init__(self,master)                                  def action1(self, path1):                           df = pd.read_csv(path1, dtype=str,nrows=999999)                            .....             

#Object instantiate

display= Action_Data(root)  display.pack()    reader = Display(root, display)  reader.pack()    pathlabel2 = Label(root)  root.mainloop()
