Class Definition Syntax

in

But first, let me warn you: this is not your typical boring tutorial.

So, what exactly is class definition syntax in Python? Well, it’s the way we create a blueprint for an object that will later be instantiated. It’s like having a cookie cutter that you use to make delicious chocolate chip cookies but instead of dough and flour, we’re using code!

Here’s how it works: first, you start with the class keyword followed by the name of your class (in CapitalizedWords notation) and a colon. Then, you indent some lines below that for the body of your class definition. Easy peasy, right?

Let me show you an example to make things clearer. Say we want to create a Dog class because who doesn’t love dogs?! 

# Creating a class called Dog
class Dog:
    # The pass statement is used as a placeholder for future code, it is optional but recommended for now
    pass

That’s right, The body of our Dog class consists of just one statement: the pass keyword. This is a placeholder that we use when we don’t have any code to write yet it allows us to run our code without Python throwing an error. But let’s not stop there! We can add some properties to our Dog class, like name and age.

To do this, we define the properties in a method called `__init__()`. This is a special method that gets executed when you create a new object from your class it’s like setting up the initial state of your object. Here’s what our updated Dog class looks like:

# Define a class called Dog
class Dog:
    # Define a method called __init__ that takes in parameters self, name, and age
    def __init__(self, name, age):
        # Set the attribute "name" of the current object to the value of the "name" parameter
        self.name = name
        # Set the attribute "age" of the current object to the value of the "age" parameter
        self.age = age
        
    # This line is optional but recommended for now
    pass

Now we can create a new object from our Dog class and assign it to a variable called `my_dog`. Here’s how:

# Creating a new object from the Dog class and assigning it to a variable called `my_dog`
my_dog = Dog("Max", 4)

# Printing a formatted string with the name and age of the dog
print(f"My dog's name is {my_dog.name} and he/she is {my_dog.age} years old.")

And that’s it, You now know how to create a class definition in Python with the proper syntax. But remember: don’t take yourself too seriously coding should be fun! It might just make someone else smile while they learn something new.
