When writing a more complicated program, you often want function stubs as place$-$holder to be implemented later.

Create stubs for the following functions $-$ they don't need to do anything, they can just have a single line of pass.

get$\_$user$\_$input doesn't take any input

get$\_$value has one parameter called index

draw$\_$rectangle has $2$ parameters $-$ x and y

fill$\_$rectangle has $3$ parameters $-$ x$,$ y$,$ and color
