For this exercise, write a program that contains an introductory docstring. This documentation should describe what the program will do $($analysis$)$ and how it will do it $($design the program in the form of a pseudocode algorithm$).$ Include suitable prompts for all inputs, and label all outputs appropriately. After you have coded a program, be sure to test it with a reasonable set of legitimate inputs.

Instructions

Light travels at $3*10$ meters per second. A light$-$year is the distance a light beam travels in one year.

Task $1$: Write a program in the file lightyear.py that expects a number of years as input and calculates and displays the value of the distance traveled in meters. $($LO: $2\mathrm{.}4)$
