Python is one of the most popular programming languages today. No matter why you choose to learn Python, you can easily teach yourself the language, even if you are a beginner with no programming experience. There are many methods and steps to follow if you want to learn Python.
Here are the steps to learn Python as a beginner:
- Understand what Python is
- Download Python
- Complete the online Python tutorial
- Check out other online resources
- Read about Python
Python is not the easiest language to learn, but it is worth the effort, especially if you want to program at a higher level. Follow the steps in this guide, and you will be on your way to programming Python at an advanced level.
1. Understand What Python Is
Let’s start with a summary of what Python is so you know what to expect.
Python is one of the most popular programming languages in the world, if not the most popular. It is a free, easy-to-write language with a focus on simple, user-friendly code. It is also an object-oriented language which means it supports classes and objects.
Another key feature of Python is that you can use it in tandem with other languages like C++. Furthermore, it is portable, meaning that you can write Python code on one operating system, say iOS, then transfer and run it on any other Python-compatible operating system with no issues.
There are multiple versions of Python since it has been around for more than three decades. Each version has its benefits, but the latest version will always have the newest features and bug fixes.
Many well-known technology companies use Python, including Google, IBM, Cisco, and Dropbox.
Here is how Python.org, the main Python website, and resource, describes the coding language:
Python is an interpreted, interactive, object-oriented programming language. It incorporates modules, exceptions, dynamic typing, very high level dynamic data types, and classes.
In addition to object-oriented programming, it also allows procedural and functional programming.
Python’s syntax is easy to understand, which is why it is a great language for beginners, and makes it easy for beginners to learn on their own. Or, if you know other languages, you can extend Python into C++ and use it as an extension for other programmable applications. Python also runs on a variety of operating systems including Windows, iOS, and Linux.
Let’s look at some differences between the current version of Python and other popular languages.
How Do Python and Other Programming Languages Differ?
Python was created in 1991 by Guido van Rossum. Van Rossum wanted a programming language that was easier to read and understand than the existing ones. When Python was first released, it used much shorter syntax to express the same functions compared to other popular languages.
If you know any other programming languages, you will have an easier time learning Python because of the similarities between the languages as well as the overlap of general syntax and concepts.
However, if you are new to programming, you will need more time and patience because you are unfamiliar with programming in general. However, it will be easier to learn a second programming language when the time comes.
Let’s compare Python to some other popular programming languages.
First, Java. It is another common first language for first-time programmers, so it is not unusual for Java and Python programmers to be beginners. Python’s program runs slower than Java, but it has a fast development time because Java is a compiled language whereas Python is a script-based language. Python will also have a shorter output code compared to Java.
C++ is another popular programming language, but it may be harder to learn. C++ is also a compiled language, but unlike Java and Python, it doesn’t use managed objects, meaning that the programmer has to be very careful about memory allocation. A flawed algorithm could end up consuming all of the resources on the computer. That’s why beginners often complain about the difficulty of C++ while professional programmers enjoy the freedom it gives them.

2. Download Python
You can’t code Python if you don’t have it on your computer!
The best thing about Python is that it is free to download, so anyone can use it. And, you probably already have a computer that is compatible with the application.
To download Python, visit Python.org and download the latest version. You can also download older versions of Python. This situation is more common if you need to run an old piece of code or library written by somebody else.
Coders tend to use version 2 or 3 depending on their preferences and what features they like. Many use version 2 because they started coding on it, and they know the ins and outs. But, as a beginner, you should start with the latest version, which is version 3.
Before you download Python, make sure you have a compatible operating system:
- iOS and iPad OS
- IBM i
- OS/390 and z/OZ
- RISC OS
If you are new to coding, you likely use Windows or iOS, both of which run just fine with Python.
3. Complete the Online Python Tutorial
Python.org offers a free online Python tutorial that walks you through the basics of the language.
The best way to go through this tutorial is by having Python open while you read through each section. That way, complete the tutorial while practicing the language. Hands-on practice is the best way to remember what you are learning.
Here are the sections in the tutorial:
- Using the Python Interpreter
- An Informal Introduction to Python
- More Control Flow Tools
- Data Structures
- Input and Output
- Errors and Exceptions
- Brief Tour of the Standard Library – Parts I and II
- Virtual Environments and Packages
- Interactive Input Editing and History Substitution
- Floating Point Arithmetic: Issues and Limitations
Every section has multiple subsections, so you will learn a lot. Once you know the basics of Python, detailed in this tutorial, you can find other tutorials that will teach you how to build apps, create websites, develop games, analyze data, or other projects you enjoy.
While this tutorial is not interactive, it will teach you all the basics of Python. If you know other coding languages, you will be familiar with some of the terminology. You may even see some overlaps between Python and the languages you know.
But, if you are new to coding, you may need to learn some coding basics before fully diving into the tutorial.
Computer Programming for Beginners on Amazon.com is a great book to read if you want to learn some coding and computer science basics. You will discover the foundations of coding, no matter what languages you learn, and read examples of popular programming languages, including Python.
