A Python class is a blueprint for creating objects (instances). It defines a set of attributes and methods that the instances of the class will have. Classes allow you to encapsulate data and functions in a single unit and promote code reuse and modularity. Each class instance can have its own attributes and methods, which can be manipulated to create objects with different behavior. Classes are defined using the “class” keyword, followed by a class name and a colon.

Class in python with example:

class City():
def __init__(self,name,city_name):
self.name=name
self.city_name=city_name

def fav_city(self):
print(“New York”)

city = City(“LA”,”Denver”)

print(city.name)

print(city.city_name)

city.fav_city()

Output: “LA”

print(city.city_name)

Output: “Denver”

dog.fav_city()

Output: “New York!”

In this example, we have defined a class named City that has two attributes: name and city_name.

The __init__ method is a special method that is called when an instance of the class is created. It sets the initial values for the attributes of the class. The fav_city method is a simple function that prints “New York!”.

Finally, we create an instance of the class with city = City("LA", "Denver"). This creates a new object of the City class, with name attribute set to “LA” and breed attribute set to “Denver”.

Here is the basic syntax for creating a class in Python:

class ClassName:
# class variables and methods
def __init__(self, arg1, arg2, …):
# constructor, used to initialize class instance
self.attribute1 = arg1
self.attribute2 = arg2
…
def method1(self, …):
# method definition
…
def method2(self, …):
# method definition
…
…

• ClassName is the name of the class, which follows the naming conventions for Python variables.
• The __init__ method is the constructor, which is called when an instance of the class is created. It accepts arguments that can be used to set the values of the instance’s attributes.
• The self parameter is a reference to the instance of the class and is used to access the attributes and methods of the class within the class definition.
• The methods are defined using the def keyword and can accept arguments, just like regular functions.
• Within the class, attributes and methods can be referred to using the self reference, e.g. self.attribute1 or self.method1().
