For today's lesson we will make a quiz game. You will need to have a program window and a 'play game' window. You will also need to know how to use radio buttons.

from tkinter import *
from tkinter.ttk import *

def main():
    # creates a Tk() object
    root = Tk()

    # sets the geometry of root window
    root.geometry("200x200")

    label = Label(master, text="This is the main window")
    label.pack(pady=10)

    button1 = Button(root,
                 text="Click to open a new window",
                 command=openNewWindow)
    button1.pack(pady=10)

    # mainloop, runs infinitely
    root.mainloop()

# function to open a new window
def openNewWindow(oldwin):
    # Toplevel object which will
    # be treated as a new window
    newRoot = Toplevel(oldwin)

    # sets the title of the
    # Toplevel widget
    newRoot.title("New Window")

    # sets the geometry of toplevel
    newRoot.geometry("200x200")

    # A Label widget to show in toplevel
    Label(newRoot, text="This is a new window").pack()

    main()

         ('Pizza', 'P'),
         ('Fish', 'F'),
         ('Cake', 'K'))

# label
label = ttk.Label(text="What do Bears like to eat?")
label.pack(fill='x', padx=5, pady=5)

# radio buttons
for size in sizes:

        text=size[0],
        value=size[1],
        variable=selected_size

root.mainloop()
