Getting Started with Python for Beginners #1: Introduction & Setup
Welcome to the first installment of our “Getting Started with Python for Beginners” series! If you’re brand new to programming or simply curious about Python, you’re in the right place. In this post, we’ll cover what Python is, why it’s one of the most popular programming languages today, and how to set up your environment so you can start coding.
What Is Python?
Python is a versatile, high-level programming language used in a wide range of applications—everything from web development and data analysis to artificial intelligence and game development, as well as scientific computing. It’s known for being:
- Beginner-Friendly: Python’s syntax reads much like English, making it easier for newcomers to understand and write code. For a gentle introduction, check out the official Python Tutorial or a beginner’s video guide on YouTube.
- Versatile: Thanks to its extensive standard library and a large ecosystem of third-party packages, Python can handle just about any task you throw at it.
- Community-Driven: Python has a huge, active community. You’ll find plenty of forums, documentation, and YouTube channels to help you learn.
Why Learn Python First?
If you’re new to programming, you might be wondering, “Why start with Python?” Here are some reasons:
- Simplicity: Python’s clear, readable syntax reduces the “cognitive load” on new programmers. You can focus on learning concepts rather than wrestling with complex syntax rules. Check out this introductory Python video to see how simple it looks.
- Immediate Results: With Python’s interactive interpreter (more on this below), you can write a line of code and see the output right away, making experimentation fun and efficient. Try following along with online Python REPL tools or watch a quick REPL tutorial.
- Transferable Skills: The programming concepts you learn in Python—like variables, loops, and functions—will form a strong foundation for any other language you learn down the road. Consider following a structured Python course to build these skills step-by-step.
Setting Up Python on Your Computer
Before we start writing code, let’s ensure you have Python installed. Python works on Windows, macOS, and Linux. The process is slightly different for each system but generally straightforward.
1. Check If You Already Have Python Installed
Open a terminal or command prompt and type:
python --version
If you see a version number (e.g., Python 3.10.7), you’re all set! If not, move on to the next step. For a quick video walkthrough, watch How to Check If Python Is Installed.
2. Installing Python
- Windows & macOS:
Visit the official Python Downloads page and get the latest stable release of Python 3.- On Windows, select the “Add Python to PATH” option during installation. Here’s a YouTube guide for Windows installation.
- On macOS, follow the installer prompts, or consider using a package manager like Homebrew. You can also check out this macOS setup video.
- Linux (Ubuntu/Debian-based):
Open your terminal and run:Many Linux distributions already come with Python, but this ensures you have an up-to-date version. For a visual guide, see this Ubuntu Python installation video. - sudo apt-get update sudo apt-get install python3
3. Verifying Your Installation
Run:
python --version
If this shows the installed version, great! On some systems, you might need to use python3 --version instead. If you need additional help, check out this verification video tutorial.
Introducing the Python Interpreter (REPL)
One of the best features of Python is its interactive interpreter, often called the REPL (Read-Eval-Print Loop). To open it, type python (or python3) in your terminal. You’ll see something like this:
Python 3.10.7 (default, Aug 31 2022, 02:13:33)
[GCC 9.4.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
The >>> prompt indicates Python is ready for input. Try typing:
print("Hello, world!")
and press Enter. You should see:
Hello, world!
You’ve just run your first line of Python code. Congrats! For more guidance on using the REPL, watch this short REPL demo video.
Choosing a Code Editor or IDE
While the Python interpreter is great for quick tests, you’ll likely want a more comfortable environment to write longer programs. Consider these tools:
- VS Code: A free, powerful editor with Python support. Check out this YouTube tutorial on setting up Python in VS Code.
- PyCharm: A dedicated Python IDE with strong code intelligence, debugging, and version control tools. Learn how to get started with PyCharm here.
- IDLE: Comes with Python and is perfect for beginners who want a simple, no-fuss environment. Here’s a quick IDLE introduction video.
Pick the tool that feels right to you. You can always switch later.
What’s Next?
In the next post, we’ll explore Python’s basic building blocks: variables, data types, and printing output. These essentials will form the foundation for everything you’ll do in Python. Before you move on, you might want to watch a basic Python concepts video to get a head start.

Wrapping Up
You’ve got Python installed and have run your first piece of code. Don’t hesitate to experiment! Try a few simple commands in the interpreter—every bit of practice increases your comfort and confidence. If you need extra practice, try following along with beginner-friendly Python exercises.
