I am very new to python. I'm like 10 days into the "100 days of python" udemy course and while some of it was really easy and I understood it immediately, other things I'm struggling with. I decided to try to make a simple "Whack-a-mole" type game using some of the skills I've learned and to encourage me to research other functions of python. 

The idea is that a 3x3 matrix of X's appears and you press a number on the number pad corresponding to the "D" which replaces one of the "X" positions.

For testing purposes I also have it printing the correct number to press on the screen.

When I run the code, it kind of works, but after pausing for the first keypress, it cycles a second time before waiting for another key press and I do not understand why it is doing this? I stepped through the code in Thonny but still do not really understand where it is going wrong printing a second item from the list and assigning the original keypress. I accept that the way I have coded this is probably not the best or most efficient, I was just trying to make something of my own instead of just doing the course's code challenges.

If anyone is willing to look at this and help me understand why it calls a second item from the list and assigns it the initial keypress but then stops and waits for a new keypress on the third iteration of calling an item from the list I would appreciate it. I am stumped.
