🧊 Objects: Instances of a Class

📖 What Is an Object?

An object is a specific instance created from a class. If the class is the cookie cutter, the object is an actual cookie. Each object has its own values for the attributes defined in the class.

🐍 Creating Objects in Python

🐍 Creating 3 zombie objects from the class

class Zombie:
    def __init__(self, health, damage, speed):
        self.health = health
        self.damage = damage
        self.speed = speed

    def attack(self, player_name):
        print(f"  {player_name} was hit for {self.damage} damage!")

    def take_damage(self, amount):
        self.health = self.health - amount
        print(f"  Zombie takes {amount} damage! HP now: {self.health}")

# CREATE objects (instances) from the Zombie class
zombie1 = Zombie(20, 3, 0.8)    # Regular Zombie
zombie2 = Zombie(40, 6, 1.2)    # Husk
zombie3 = Zombie(80, 12, 1.5)   # Zombie Villager

# Each object has its OWN values
print("=== Three Zombie Objects ===")
print(f"zombie1: HP={zombie1.health}, DMG={zombie1.damage}")
print(f"zombie2: HP={zombie2.health}, DMG={zombie2.damage}")
print(f"zombie3: HP={zombie3.health}, DMG={zombie3.damage}")

# Each object can use the class methods
print()
print("zombie1 attacks:")
zombie1.attack("Steve")

print()
print("zombie3 takes damage:")
zombie3.take_damage(25)
print(f"zombie3 HP is now: {zombie3.health}")
print(f"zombie1 HP is still: {zombie1.health}  (not affected!)")

🎯 Key Point

Each object is independent. Changing zombie3's health does NOT affect zombie1. They are separate instances with their own data, even though they were all created from the same class.
