Why isn't .ico file defined when setting window's icon?

Question

When I tried to change the window icon in the top left corner from the ugly red \"TK\" to my own favicon using the code below, Python threw an error:

from tk         


        

Answer 1

#!/usr/bin/env python
import tkinter as tk

class AppName(tk.Frame):
    def __init__(self, master=None):
        tk.Frame.__init__(self, master)
        self.grid()
        self.createWidgets()

    def createWidgets(self):
        self.quitButton = tk.Button(self, text='Quit', command=self.quit)
        self.quitButton.grid()

app = AppName()
app.master.title('Title here ...!')
app.master.iconbitmap('icon.ico')
app.mainloop()

it should work like this !
