You use the Scale widget whenever you need to choose a precise value from a range of values. It includes a sliding bar that allows picking values by dragging clockwise or from up to down, based on how your sliding bar is oriented.

In this tutorial, we'll go through making a Tkinter scale.

Examples of the Tkinter Scale

Example 1: A horizontal Tkinter scale

from tkinter import *

def select():sel = "Value = " + str(v.get())

label.config(text=sel)

top = Tk()

top.geometry("300x200")

v = DoubleVar()

scale = Scale(top, variable=v, from_=1, to=100, orient=HORIZONTAL)

scale.pack(anchor=CENTER)

btn = Button(top, text="Choose Value", command=select)

btn.pack(anchor=CENTER)

label = Label(top)

label.pack()

top.mainloop()

Example 2: A vertical Tkinter scale
