class Car:
  # Initializting Attributes of Class Car
  def __init__(self, color, brand, model):
    self.color = color
    self.brand = brand
    self.model = model

  def repaint(self, new_color):
    self.color = new_color


# Creating Object called "MyCar" along with attributes
MyCar = Car("OrchidWhite", "Honda", "Amaze")

# Extracting Information from the "My Car" Object
print(f"My Car is a {MyCar.color} {MyCar.brand} {MyCar.model}")

# My Car Repatined with Metallic Blue
MyCar.repaint("MetallicBlue")

# Extracting Information from the "My Car" Object
print(f"After Repaint My Car is a {MyCar.color} {MyCar.brand} {MyCar.model}")

My Car is a OrchidWhite Honda Amaze
After Repaint My Car is a MetallicBlue Honda Amaze

Inheritance Implementation

Electric Car

class ElectricCar(Car):
  # Initializting Attributes of Class Eletric Car
  def __init__(self, color, brand, model,battery_capacity=0):
    super().__init__(color,brand,model)
    self.battery_capacity = battery_capacity
  
  def charge_battery(self, charge_amount):
    self.battery_capacity += charge_amount

Fuel Car

class FuelCar(Car):
  # Initializting Attributes of Class Fuel Car
  def __init__(self, color, brand, model,TankSize=0):
    super().__init__(color,brand,model)
    self.TankSize = TankSize
    self.fuel_level = 0
  
  def RefuelTank(self, fuel_amount):
   if self.fuel_level + fuel_amount > self.TankSize:
      print("Cannot refuel beyond tank capacity.")
   else:
      self.fuel_level += fuel_amount

Inheritance Implementation Output

Electric Car

PriyasCar = ElectricCar("Red", "Tesla", "Model 3", battery_capacity=75)

# Extracting Information from the "Priyas Car" Object
print(f"Priyas Car is a {PriyasCar.color} {PriyasCar.brand} {PriyasCar.model}")

# My Car Repatined with Metallic Blue and Charged to 25%
PriyasCar.repaint("MetallicBlue")
PriyasCar.charge_battery(25)

# Extracting Information from the "Priyas Car" Object
print(f"After Repaint Priyas Car is a {PriyasCar.color} {PriyasCar.brand} {PriyasCar.model}. Having Current Capacity {PriyasCar.battery_capacity}")

Priyas Car is a Red Tesla Model 3
After Repaint Priyas Car is a MetallicBlue Tesla Model 3. Having Current Capacity 100

Fuel Car

MyCar = FuelCar("OrchidWhite", "Honda", "Amaze", TankSize=40)

# Extracting Information from the "My Car" Object
print(f"My Car is a {MyCar.color} {MyCar.brand} {MyCar.model} with TankSize {MyCar.TankSize} Ltrs")

MyCar.RefuelTank(30)

print(f"My Car is a {MyCar.color} {MyCar.brand} {MyCar.model} with TankSize {MyCar.TankSize} Ltrs. \n Current Fuel Level is {MyCar.fuel_level} ")

My Car is a OrchidWhite Honda Amaze with TankSize 40 Ltrs
My Car is a OrchidWhite Honda Amaze with TankSize 40 Ltrs. 
 Current Fuel Level is 30
