Question

Driving costs - functions

Learning Objectives

  • Create a function to match the specifications
  • Use floating-point value division

Instructions

Driving 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(f'{your_value:.2f}')

Ex: If the input to your program is:

20.0 3.1599

the output is:

The gas cost for 10 miles is 1ドル.58 The gas cost for 50 miles is 7ドル.90 The gas cost for 400 miles is 63ドル.20

Your program must define and call the 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 3.1599

the function returns:

7.89975

def 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.

Hint: To calculate how many gallons I will spend to drive 1 mile I will divide 1 by a car's miles/gallon parameter.

Note: Pay attention to the distinction of what the function expects and is supposed to do versus what the program needs to collect and do. In this lab, the function has 3 parameters, whereas the program collects only 2 input values because the miles are already pre-determined (i.e., hard-coded) inside of its code.

# Define your function here.

if __name__ == '__main__':
# Type your code here.
