Class in Python
To create a class in Python, you can use the class keyword followed by the name of the class. The class definition should include a __init__ method, which is a special method in Python that is called when an instance of the class is created.
Here is an example of a simple class definition in Python:
class Dog:
def __init__(self, name, breed):
self.name = name
self.breed = breed
def bark(self):
print("Woof!")
This class definition creates a class called Dog that has two attributes: name and breed, and a method called bark. The __init__ method is called when an instance of the class is created, and it initializes the attributes of the instance.
To create an instance of the Dog class, you can call the class like a function and pass in the required arguments:
dog1 = Dog("Fido", "Labrador")
You can access the attributes of an instance using the dot notation:
print(dog1.name) # Output: "Fido"
print(dog1.breed) # Output: "Labrador"
And you can call the methods of an instance using the dot notation and parentheses:
dog1.bark() # Output: "Woof!"
You can define additional methods and attributes in the class definition as needed. You can also use inheritance to create a new class that is based on an existing class, and override or extend its behavior as needed.
