Question

Implement a class, Car, which represents a car and can simulate its fuel usage. The fuel efficiency should be specified when the object is created. The class should contain the following.

Constructor
1) init_(self, efficiency)
Instance Variables
a) fuelEfficiency fuel efficiency (measured in km/ litres); float
b) fuel amount of gas in tank (litres) with an initial value of zero; float
Methods
i) drive (distance) -simulates driving the car for certain distance, reducing the fuel level in the gas tank based on the fuel efficiency
ii) getGaslevel() - returns the current fuel level
iii) addGas (amount) —adds amount to instance variable fuel

Answer 1

The student's question involves creating a Car class with a constructor, instance variables for fuel efficiency and amount of fuel, and methods for driving, reporting fuel level, and adding gas.

Step-by-step explanation:

The student is asking for the implementation of a Car class in a programming context, which simulates fuel usage based on given fuel efficiency. This involves creating a constructor with fuelEfficiency, an instance variable to hold the amount of fuel, and methods to drive the car, report fuel level, and add gas.

Here is an example of how the Car class may be implemented:

class Car:
def __init__(self, efficiency):
self.fuelEfficiency = efficiency
self.fuel = 0.0

def drive(self, distance):
fuel_needed = distance / self.fuelEfficiency
if fuel_needed <= self.fuel:
self.fuel -= fuel_needed
return True
else:
return False # not enough fuel

def getGasLevel(self):
return self.fuel

def addGas(self, amount):
self.fuel += amount
