how do I create a python program with a main function and a custom module named rect that defines three custom functions about rectangles as follows:

• a value-returning function that takes a rectangle's dimensions as parameters and returns the perimeter.


• a void function that takes a rectangle's dimensions as parameters and prints the area.


• a value-returning function that takes a rectangle's dimensions as parameters and
  returns
  the diagonal length.

In the main function, import your custom module, prompt the user for the dimensions of a rectangle, and then use all three module functions.
