if __name__ == '__main__': main()

1. Update the window title to CSCI351 - Course Registration

2. Change the Login button color. Hint: Use hex color codes

3. Update the code to print Hello username- when the Login button is clicked.

4. Add a new button called Logout that prints Goodbye when clicked.

Can you help me to this python code at number 3 and 4?
