Class User

In Python, a class is a blueprint for creating objects. A class encapsulates data for the object and methods to manipulate that data. Here's a simple example of a User class in Python. This class will have two attributes: name and email, and a method to display the user's information.

class User:
   def __init__(self, name, email):
       self.name = name
       self.email = email
   def display_user_info(self):
       print(f"Name: {self.name}, Email: {self.email}")

Here's a breakdown of the components:

  • class User:: This line defines the class named User.
  • def __init__(self, name, email):: This is the constructor of the class. It's automatically called when a new instance of the class is created. It takes three parameters: self, name, and email. The self parameter is a reference to the current instance of the class and is used to access variables that belong to the class. name and email are the parameters passed to the constructor to initialize the attributes of the object.
  • self.name = name and self.email = email: These lines set the name and email attributes of the object to the values passed during object creation.
  • def display_user_info(self):: This method displays the information of the user. The self parameter is a reference to the instance calling the method, which allows access to the attributes of the object.

To create a User object and use its method, you would do the following:

# Creating an instance of the User class
user1 = User("John Doe", "johndoe@example.com")
# Calling a method of the User class
user1.display_user_info()

This will output:

Name: John Doe, Email: johndoe@example.com

Classes can be expanded with more attributes and methods to suit your needs, offering a powerful way to create complex data structures and functionalities within your programs.
