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")
