how can I Write a GUI program that calculates a car’s gas mileage. The
program’s window should have Entry widgets that let the user
enter the number of gallons of gas the car holds, and the
number of miles it can be driven on a full tank. When a
Calculate MPG button is clicked, the program should display
the number of miles that the car may be driven per gallon of
gas. Use the following formula to calculate miles-per-gallon:

MPG =
miles/gallons

In python?
