Tkinter Button Example
Python tkinter Button
When you are building a GUI application, button is one the building block that makes your application interactive.
In this tutorial, we shall learn how to implement Button in Python GUI using tkinter Python library.
Syntax to create Tkinter Button
The syntax to add a Button to the tkinter window is:
mybutton = Button(master, option=value)
mybutton.pack()Where master is the window to which you would like to add this button. tkinter provides different options to the button constructor to alter its look.

1. Create Button in Tkinter
In the following example, we will create a tkinter button with the following properties.

| bg | '#0052cc' |
| fg | '#ffffff' |
| activebackground | '#0052cc' |

Python Program
from tkinter import *
gui = Tk(className='Python Examples - Button')
gui.geometry("500x200")
# create button
button = Button(gui, text='My Button', width=40, height=3, bg='#0052cc', fg='#ffffff', activebackground='#0052cc', activeforeground='#aaffaa')
# add button to gui window
button.pack()
gui.mainloop() When you run this python program, you will get the following Window.
