How to Open a Window in Python

by

For this you can use tkinter:

from tkinter import Tk, Frame, BOTH

class Example(Frame):

    def __init__(self, parent):
        Frame.__init__(self, parent, background="green")   

        self.parent = parent

        self.parent.title("Window")
        self.pack(fill=BOTH, expand=1)

root = Tk()
root.geometry("500x500")
app = Example(root)
root.mainloop()
