Create a program called gas$\_$calc.py$,$ which asks the user $1)$ the number of miles they drove on a trip, $2)$ the number of gallons of gas they used, and $3)$ the price of gas per gallon. The program uses their input to figure out and display the cost of the trip & the miles per gallon $($MPG$)$ for the trip. See output format below.

Ongoing challenges: what goes into the $.$py file comments, and what goes into your PDP document? Double check all standard requirements for the PDP & $.$py file.
