Creating Simple window in tkinter

• We need to import Tk class from tkinter module.
• Instantiation of Tk class results a “window.
• The following code snippet display the frame with title ‘tk’

from tkinter import Tk

class GUI:
    def main():
        frame = Tk()
        return

GUI.main()

• We can write GUI programs without using classes(object orientation).
• mainloop()is used to represent the execution point(when multiple frames) of application.
• When we define the code in single frame, calling mainloop() is optional.

from tkinter import Tk
frame = Tk()
frame.mainloop()

Using the pre-defined functionality of “Tk” class, we can set properties to Frame.

from tkinter import Tk
frame = Tk()
frame.title("GUI")
frame.geometry("500x300")
frame.mainloop()
