Problem

Write a recursive function called count$\_$by that takes an integer as a parameter. Return the result of recursively counting by seven as many times as the parameter.

Expected Output

If you test your function with the following code:

# test code below if $\_\_$name$\_\_=="\_\_$main$\_\_"$: example$\_$num $=3$ print$($count$\_$by$($example$\_$num$))$

It should produce the output:

$21$

What doesif $\_\_$name$\_\_=="\_\_$main$\_\_"$:mean?

If you test your function with the following code:

# test code below if $\_\_$name$\_\_=="\_\_$main$\_\_"$: example$\_$num $=9$ print$($count$\_$by$($example$\_$num$))$

It should produce the output:

$63$
