Question

Write a Python program that computes the fuel efficiency of a multi-leg journey. The program will first prompt for input for the starting odometer reading and then get information about the series of legs on the journey. For each leg, the user enters the current odometer reading and the amount of fuel used in liters (separated by a blank space). The user signals the end of the trip with a blank line. The program should print out the kilometers per liter achieved on each leg (to 1 decimal precision). The program should also print out for the trip the total distance, total fuel consumed, and fuel efficiency for the entire trip.

See the example below:

>>>Enter initial odometer reading: 1000
>>>Enter leg info (odometer reading, fuel used): 1040 2
20.0 km per liter
>>>Enter leg info (odometer reading, fuel used): 1080 3
13.3 km per liter
>>>Enter leg info (odometer reading, fuel used): 1190 10
11.0 km per liter
>>>Enter leg info (odometer reading, fuel used): 1250 5
12.0 km per liter
>>>Enter leg info (odometer reading, fuel used):
Total distance traveled = 250 km. Total fuel used = 20 liters. Fuel efficiency = 12.5 km per liter.

Using PyCharm and please use basic while, for and if loop.

Answer 1

Code starts here :

initial = int(input("Enter initial odometer reading: "))
input_values = input("Enter leg info (odometer reading, fuel used): ")
last, total_fuel = initial,  0
while input_values != "":
    reading, fuel = (int(x) for x in input_values.split())
    print(round((reading-last)/fuel, 1), "km per liter")
    total_fuel += fuel
    input_values = input("Enter leg info (odometer reading, fuel used): ")
    last = reading
print("Total distance traveled =", last-initial, "km. Total fuel used =", total_fuel, "liters. Fuel Efficiency =", round((last-initial)/total_fuel, 1), "km per liter.")

We first take initial odometer reading and declare variables for maintaining last reading, total_fuel and current reading and current fuel.

We maintain a while loop with condition that input should not be empty. If it is empty, then loop will break, and final outputs wiil be printed.

On line 5, the code splits the input into two, reading and fuel, and converts into integer value.

round() function will round the float value to the given precision, here 1.
