How to write a Python program that calculates the brightness of a star, given its distance, from the observer and luminosity that contains:

inverse_square(d)

This function returns an inverse square law value of a given distance d. The formula for the inverse square law is val=14πd2.

brightness(d, L)

A function brightness(d, L) that returns the brightness of a star at a given distance d and luminosity L. The formula for brightness is b=L∗14πd2

You must call your inverse_square(d) function as part of this function’s operation.

main()

Write a main() asks the user for the distance, in meters, and luminosity of that star, in watts, and prints the calculated brightness, in units of Watts/m^2.
