simple tkinter program in python code example

Example 1: tkinter basic

from tkinter import Tk, Label, Button

class MyFirstGUI:
    def __init__(self, master):
        self.master = master
        master.title("A simple GUI")

        self.label = Label(master, text="This is our first GUI!")
        self.label.pack()

        self.greet_button = Button(master, text="Greet", command=self.greet)
        self.greet_button.pack()

        self.close_button = Button(master, text="Close", command=master.quit)
        self.close_button.pack()

    def greet(self):
        print("Greetings!")

root = Tk()
my_gui = MyFirstGUI(root)
root.mainloop()

Example 2: tkinter tutorial

# Python 3.x
import tkinter
top = tkinter.Tk()
# Code to add widgets will go here...
top.mainloop()

# I recommend creating each tkinter window as a child class to a frame.
# This keeps all methods related to the window encapsulated, and makes
# your code alot more understandable and readable :)

Example 3: tkinter tutorial

#Import
import tkinter as tk
from tkinter import ttk
#Main Window
window=tk.Tk()
#Label
label=ttk.Label(window,text="My First App")
#Display label
label.pack()
#Making sure that if you press the close button of window, it closes.
window.mainloop()
