Question

Python

Consider the GUI below (3 Labels and 3 Radiobuttons) which has been produced with a Python program using the Tkinter library.  

You are required to write a Python program to produce this interactive GUI.

Your GUI must replicate the example above as closely as possible, including the same widgets displayed in the sample positions on the GUI, using the same colours, shapes and relative sizes. (Note that the GUI border in the sample output does not need to be replicated as this is an operating system environment setting.)

Your GUI must not contain any elements that are not in the example provided above, and must interact with the user as follows:

• Initially, the Labels are grey and display no text.
• Whenever Radiobutton 1 is selected by the user, the first Label changes colour and displays the text "Ready..."
• Whenever Radiobutton 2 is selected by the user, the second Label changes colour and displays the text "Set..."
• Whenever Radiobutton 3 is selected by the user, the third Label changes colour and displays the text "...GO!"

THE FOLLOWING IS THE START OF THE PYTHON CODE:

#----------------------------------------------------------------
#
# 3 labels, 3 radiobuttons (as per diagram)
# Initially, the Labels are grey and display no text.
# When Radiobutton 1 is selected by the user, the first Label
# changes colour and displays the text "Ready..."
# When Radiobutton 2 is selected by the user, the second Label
# changes colour and displays the text "Set..."
# When Radiobutton 3 is selected by the user, the third Label
# changes colour and displays the text "...GO!"
#----------------------------------------------------------------

# Import the Tkinter functions
from tkinter import *

# Create a window
the_window = Tk()

# Give the window a title
the_window.title('Label Changer')

# PUT YOUR CODE HERE-------------------------------------------------#

# -------------------------------------------------------------------#

# Start the event loop
the_window.mainloop()
