What is the difference between class and instance methods?

📝 Understanding the Difference Between Class and Instance Methods

Hitting us with some tech lingo, are we? 🕶️ Today, we're diving into the difference between class methods and instance methods. 🏄‍♂️ So, buckle up and get ready for some code chit-chat! 💻

What's the Deal with Class Methods and Instance Methods?

So, imagine you have a class called Dog. 🐶 We all love dogs, right? 🐕 Now, this class has some attributes like name, age, and breed. Each Dog object will have different values for these attributes.

• An instance method is like a personalized doggy trick 🐾 that can be performed by a specific instance (object) of the Dog class. It can operate on the individual attributes of that instance. For example, an instance method bark() will make a specific dog bark, like "Woof! Woof! 🐾🐾".

• On the other paw, a class method is like a universal doggy trick 🐩 that can be performed by all the dogs in the Dog class (all instances). It can't operate on individual attributes because it doesn't know which dog it's operating on. 🤷‍♂️ For example, a class method rollOver() will make all dogs roll over, regardless of their names, ages, or breeds. 🔄

Confusion Unleashed: Are Instance Methods Just Getters and Setters?

Not exactly, my tech-savvy friend! While instance methods can indeed be used for getters and setters, they are not limited to just that. They can do so much more! 🚀

Instance methods can perform any operation on the attributes of a specific object. For example, an instance method feed() could take the name and increase the age of the dog by one. 🍖🎂

Additionally, they can also interact with other objects, perform calculations, and return values based on the logic defined within them. So, don't underestimate the power of instance methods! 🔥

Let's Implement Some Code

To make things more paw-some, here's an example in Python 🐍 to help solidify our understanding:

class Dog:
    def __init__(self, name, age, breed):
        self.name = name
        self.age = age
        self.breed = breed

    def bark(self):
        print(f"{self.name} says: Woof! Woof!")

    @classmethod
    def rollOver(cls):
        print("All dogs are rolling over!")

# Creating two dogs
dog1 = Dog("Max", 3, "Labrador")
dog2 = Dog("Bella", 5, "Poodle")

# Calling instance method
dog1.bark()  # Output: Max says: Woof! Woof!

# Calling class method
Dog.rollOver()  # Output: All dogs are rolling over!
