Tkinter root window not coming up

Question

In my program i have tried to get a Tk window to come up yet it does not come up.
I have called my window root and i have put in an event loop, yet it still does
show. I have looked all over the internet for a solution but it appers to cease
to exist.

This is a code snippet from the beggining of the program:

def NumberGuessingGame():

    z       = 0
    b       = True
    h       = 0
    name    = 1
    root    = Tk()
    frame1  = Frame( root, width = 400, height = 400 )

    credits = Label( frame1, text = 'NumberGuessingGame.\nAuthor: ***********\nVersion: 6.0', fg = 'red' )
    credits.grid(row = 0)

and this is the code snippet from the end of the program:

v2 = True

while v2 == True:

    v1 = input( 'Would you like to play the game? ' )

    if v1 == 'y' or v1 == 'yes':
        NumberGuessingGame()
        continue

    elif v1 == 'n' or v1 == 'no':
        print( 'The game will now exit.' )
        break

    else:
        print( 'The game will now exit.' )
        break

input( "Press <ENTER> to close program." )

root.mainloop()

Answer 1

A: your code never gets into .mainloop()

your code-logic preceding the root.mainloop() fortunately prevents from entering the Tkinter GUI

Answer 2

you need contructor like so:

def __init__(root):

this makes your code be able to run and call root.mainloop() to make a tk window
