Classes and Objects in Python Programming

czwartek, 8 czerwiec 23, 17:05

Python, a versatile and powerful programming language, supports object-oriented programming (OOP) paradigms. At the core of OOP in Python are classes and objects, which provide a structured way to organize and model complex systems. In this blog post, we will explore the concepts of classes and objects in Python, their relationship, and how they enable code reusability and modularity.

What are Python Classes?

A class in Python is a blueprint or template that defines the attributes (data) and behaviors (methods) of objects. It serves as a blueprint for creating multiple instances of objects with similar characteristics. Python Classes in Pune encapsulate data and related functions, allowing for clean and modular code organization.

Defining a Class:

In Python, classes are defined using the classkeyword, followed by the name of the class. Let's take a simple example of a Personclass:

fff; --tw-ring-color: rgba(69,89,164,.5); --tw-ring-offset-shadow: 0 0 transparent; --tw-ring-shadow: 0 0 transparent; --tw-shadow: 0 0 transparent; --tw-shadow-colored: 0 0 transparent; --tw-blur: ; --tw-brightness: ; --tw-contrast: ; --tw-grayscale: ; --tw-hue-rotate: ; --tw-invert: ; --tw-saturate: ; --tw-sepia: ; --tw-drop-shadow: ; --tw-backdrop-blur: ; --tw-backdrop-brightness: ; --tw-backdrop-contrast: ; --tw-backdrop-grayscale: ; --tw-backdrop-hue-rotate: ; --tw-backdrop-invert: ; --tw-backdrop-opacity: ; --tw-backdrop-saturate: ; --tw-backdrop-sepia: ; margin-top: 1.25em; margin-bottom: 1.25em; background-color: rgb(247, 247, 248);">class Person: def __init__(self, name, age): = name self.age = age def greet(self): print(f"Hello, my name is {} and I am {self.age } years old.")

Understanding variable scoping rules is essential for writing efficient and bug-free code in any programming language. Python, a popular and versatile language, follows specific scoping rules that govern how variables are accessed and managed within different contexts. In this blog post, we will explore the basic scoping rules for Python Course in Pune and delve into the concepts of global, local, and nonlocal scopes.

Global Scope:

In Python, variables declared outside of any function or class have a global scope. Global variables can be accessed and modified from anywhere within the program, including inside functions or classes. They retain their values ​​throughout the program's execution.
