This Programming Language Python Tutorial is very well suited for beginners and also for experienced programmers. This specially designed free Python tutorial will help you learn Python programming most efficiently, with all topics from basics to advanced (like Web-scraping, Django, Learning, etc.) with examples.

What is Python?

Python is a high-level, general-purpose, and very popular programming language. Python programming language (latest Python 3) is being used in web development, and Machine Learning applications, along with all cutting-edge technology in Software Industry. Python language is being used by almost all tech-giant companies like – Google, Amazon, Facebook, Instagram, Dropbox, Uber… etc.

Writing your first Python Program to Learn Python Programming

There are two ways you can execute your Python program:

  1. First, we write a program in a file and run it one time.
  2. Second, run a code line by line.

Here we provided the latest Python 3 version compiler where you can edit and compile your written code directly with just one click of the RUN Button. So test yourself with Python first exercises.

Python
# Python Program to print Hello World
print("Hello World! I Don't Give a Bug")

Output
Hello World! I Don't Give a Bug

Let us now see what will you learn in this Python Tutorial, in detail:

The first and foremost step to get started with Python tutorial is to setup Python in your system.

Python Tutorial

Below are the steps based your system requirements:

Additionally, we’ll unravel the intricacies of assignment operators for efficient variable assignment and updating. Lastly, we’ll demystify membership and identity operators, such as in and is, enabling you to test for membership in collections and compare object identities with confidence.

Python Conditional Statement

These statements are pivotal in programming, enabling dynamic decision-making and code branching. In this section of Python Tutorial, we’ll explore Python’s conditional logic, from basic if…else statements to nested conditions and the concise ternary operator. We’ll also introduce the powerful match case statement, new in Python 3.10. By the end, you’ll master these constructs, empowering you to write clear, efficient code that responds intelligently to various scenarios. Let’s dive in and unlock the potential of Python’s conditional statements.

Python Loops

Here, we’ll explore Python’s loop constructs, including the for and while loops, along with essential loop control statements like break, continue, and pass. Additionally, we’ll uncover the concise elegance of list and dictionary comprehensions for efficient data manipulation. By mastering these loop techniques, you’ll streamline your code for improved readability and performance.

Python Functions

Functions are the backbone of organized and efficient code in Python. Here, we’ll explore their syntax, parameter handling, return values, and variable scope. From basic concepts to advanced techniques like closures and decorators. Along the way, we’ll also introduce versatile functions like range(), and powerful tools such as *args and **kwargs for flexible parameter handling. Additionally, we’ll delve into functional programming with map, filter, and lambda functions.

Python OOPs Concepts

In this segment, we’ll explore the core principles of object-oriented programming (OOP) in Python. From encapsulation to inheritance, polymorphism, abstract classes, and iterators, we’ll cover the essential concepts that empower you to build modular, reusable, and scalable code.

Python Exception Handling

In this section of Python Tutorial, we’ll explore how Python deals with unexpected errors, enabling you to write robust and fault-tolerant code. We’ll cover file handling, including reading from and writing to files, before diving into exception handling with try and except blocks. You’ll also learn about user-defined exceptions and Python’s built-in exception types.

Python Packages or Libraries

The biggest strength of Python is a huge collection of standard libraries which can be used for the following:

Python Collections

Here, we’ll explore key data structures provided by Python’s collections module. From counting occurrences with Counters to efficient queue operations with Deque, we’ll cover it all. By mastering these collections, you’ll streamline your data management tasks in Python.

Python Database Handling

In this section you will learn how to access and work with MySQL and MongoDB databases

Python vs. Other Programming Languages
