Purpose: Familiarize yourself with some basic list syntax and usage.

Degree of Difficulty: Moderate

Let$$s have some fun with polkadots! You$$ll write a program where the user can click the mouse to place circles on the canvas, and with the press of a key, all of the circles will randomly change color.

Here is how your program should behave:

$$ Start with an empty $400$x$400$ canvas with a light grey background

$$ When the user clicks the mouse: A new white circle appears where the mouse was clicked.

$$ When the user presses the $$p$$ key: All of the circles on the canvas change color to a random color!

$($It is okay if$,$ by random chance, a circle remains the same color as before.$)$
