Raspberry Pi 3 GUI - Part 5 - 3 Control Buttons and Text with Tkinter

3 Control Buttons with aligned text using Tkinter

This program creates 3 buttons that will be used to control 3 LED's. The text is aligned to the buttons using ".grid" and will eventually display the state of the LED.

(1) Enter this code into your Python 3 window

#! /usr/bin/env python

from Tkinter import*

window = Tk()
window.title( '')

# create text items
red_led_text = Label(window, relief='sunken', width=15)
yellow_led_text = Label(window, relief='sunken',width=15)
green_led_text = Label(window, relief='sunken', width=15)

# create buttons for controlling LED's
red_led_button = Button(window)
yellow_led_button = Button(window)             
green_led_button = Button(window)

# set initial button text
red_led_button.configure(text='RED (ON / OFF)', command=exit)
yellow_led_button.configure(text='YEL (ON / OFF)', command=exit)
green_led_button.configure(text='GRN (ON / OFF)', command=exit)

# set initial text values
red_led_text.configure(text='RED LED IS OFF')
yellow_led_text.configure(text='YEL LED IS OFF')
green_led_text.configure(text='GRN LED IS OFF')

# set location of buttons
red_led_button.grid(row=1, column=1,padx=10)
yellow_led_button.grid(row=2, column=1,padx=10)
green_led_button.grid(row=3, column=1,padx=10)
# location of text                         
red_led_text.grid(row=1, column=3,padx=10 )
yellow_led_text.grid(row=2, column=3,padx=10 )
green_led_text.grid(row=3, column=3,padx=10 )


My code looks like this:
