Move the code from open_window2() into a class in settings.py, e. g.


import tkinter as tk # avoid star-import

class SettingsWindow(tk.Toplevel): # Class names start with uppercase letter
                                   # Prefer self-explaining names
    def __init__(self, root):
        super().__init__(root)
        self.title('New window')
        self.geometry('262x65+200+250')
        self.transient(root)

Then use it in your main script:

import settings
