your code always produces $8$ repetitions of the basic unit. Now modify your code so that the required number of repetitions is held in a variable number$\_$of$\_$units, where number$\_$of$\_$units is initialised to $4$ in this case but can be initialised to a different value as required.

Run your program using different values of number$\_$of$\_$units to test that it produces the expected output.
