I'm a newbie to python so please bear with me. I was making a class that contains the make, model, and fuel of a car and was experimenting with the set and get methods to try and learn their use. The issue I'm running into is when I try to update my tank attribute by running my setFuel method and print out the updated fuel integer I get error tank is not defined even though I defined it all the way above. Why is this occurring and how can I fix it. I added comments all over my code to explain what I tried to do to help you understand my code. Any help is appreciated thanks in advance.
class Car: tank = 0 #to keep track of fuel make = "" model = "" #to keep track of model def __init__(self, make, model, fuel): self.make = make self.model = model self.fuel = fuel #returns the amout of fuel currently in the tank(as an integer) def getFuel(self): return int(self.fuel) #sets the amounts of fuel currently in the tank(as an integer) def setFuel(self, tank): self.tank = int(tank) #returns the make and model of the car as a string def getType(self): return str(self.make),(self.model) def printFuel(self): print(self.fuel) #Instantiate a new Car in a variable myCar = Car("Ford", "Escort", 10) yourCar = Car("Ford", "Escape", 14) #print statement that prints the result of the "getFuel" #method of the "myCar" object myCar.printFuel() yourCar.printFuel() #Change the "tank" attribute to modify the fuel in the tank using #setFuel method of the "myCar" and "yourCar" object #subtract 7 from from the tank myCar.setFuel(tank-7) #subtract 5 from the tank yourCar.setFuel(tank-5) #print statement that prints the result of the "getFuel" #method of the "myCar" and "yourCar" object print(myCar.getFuel()) print(yourCar.getFuel()) print(myCar.getType()) print(yourCar.getType())
