Implement a GUI widget class RoundRobin that consist of an Entry widget and a Button widget labeled "Next". The class constructor should take a non-empty list as an input argument, for example:

>>> lst = ['Zoe', 'Yannick', 'Xena', 'Wendy', 'Vince']

>>> RoundRobin(lst).mainloop()

The Entry widget should display nothing at startup:

When the Next button is clicked, the first item in the list should be displayed:

Clicking the Next button again should result in the next list item being displayed:

In general, every button click should result in the next list item being displayed, in round robin fashion.

Test your class using the following statement in your final.py file:

RoundRobin().mainloop()

Please read and answer it in the way its asked. Thank you
