How to do it...

This program has Spinbox and Scale for selecting an integer value from 0 to 5:

import tkinter as tk 
 
class App(tk.Tk):
    def __init__(self): 
        super().__init__() 
        self.spinbox = tk.Spinbox(self, from_=0, to=5) 
        self.scale = tk.Scale(self, from_=0, to=5, 
                              orient=tk.HORIZONTAL) 
        self.btn = tk.Button(self, text="Print values", 
                             command=self.print_values) 
        self.spinbox.pack() 
        self.scale.pack() 
        self.btn.pack() 
 
    def print_values(self): 
        print("Spinbox: {}".format(self.spinbox.get())) 
        print("Scale: {}".format(self.scale.get())) 
 
if __name__ == "__main__": 
    app = App()
    app.mainloop()

In the preceding code, for debugging purposes, we added a button that prints the value of each widget when you click on it:
