Your Tasks

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 $3**{10}^8$ 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: $2\mathrm{.}4)$
