5.19 LAB: Driving costs - functionsDriving is expensive. Write a program with a car's miles/gallon and gas dollars/gallon (both floats) as input, and output the gas cost for 10 miles, 50 miles, and 400 miles. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:print('{:.2f}'.format(your_ value))Ex: If the input is:20.03.1599the output is:1.587.9063.20Your program must define and call the following driving_cost() function. Given input parameters driven_miles, miles_per_gallon, and dollars_per_gallon, the function returns the dollar cost to drive those miles. Ex: If the function is called with:50 20.0 3.1599the function returns:7.89975def driving_cost(driven_miles, miles_per_gallon, dollars_per_gallon)Your program should call the function three times to determine the gas cost for 10 miles, 50 miles, and 400 miles. Note: This is a lab from a previous chapter that now requires the use of a function.
