Write a program using the elif keyword that determines if what the user entered is a primary color $($red$,$ blue, or yellow$).$ If yes, print $\_$ is a primary color, where the blank is the string they entered. If no$,$ print $\_$ is not a primary color, where the blank is what the user entered.

Note: You could write this program with a single compound conditional if but make sure you know how to write it using elif.
