Design a function called get$\_$range$\_$of$\_$factors that two integers: the first representing a starting point and the second

representing an end point. The function should return a string containing rows with the factors all numbers from the given

start point $($inclusive$)$ to the given end point $($not inclusive$).$

All of the factors of a given number from smallest to biggest should be separated by commas $(,).$ Each set of factors

should end with a newline.

The returned string must be formatted exactly as demonstrated in the example below, with commas between values and

no additional white space or trailing commas.

The function should assume the integers passed as arguments are greater than $0.$

For example, if the function is called as: get$\_$range$\_$of$\_$factors $(10,13)$ it should return the value:

${?}^{\text{'}}1,2,5,\frac{10}{?}$

$1,\frac{11}{?}$

$1,2,3,4,6,\frac{12}{?}$

${?}^{\text{'}}$ which if printed would look like the following:

$111$

NOTE: you may not use the following Python String functions: join, strip, rstrip, $15$trip

TIP: think about how to use the function you already wrote!
