Python programming tutorial

This is a concise Python 3 programming tutorial for people who think that reading is boring. I try to show everything with simple code examples; there are no long and complicated explanations with fancy words. If you have never programmed before click here to find out what programming is like and get started.

This tutorial is aimed at people with no programming experience at all or very little programming experience. If you have programmed a lot in the past using some other language you may want to read the official tutorial instead.

You can use Python 3.3 or any newer Python with this tutorial. Don't use Python 2. If you write a Python 2 program now someone will need to convert it to Python 3 later, so it's best to just write Python 3 to begin with. Python 3 code will work just fine in Python 4, so you don't need to worry about that. Python 2 also has horrible Unicode problems, so it's difficult to write Python 2 code that works correctly with non-English characters (like π and ♫).

List of contents

The tutorial consists of two sections:

Basics

This section will get you started with using Python and you'll be able to learn more about whatever you want after studying it.

1. What is programming?
2. Installing Python
3. Getting started with Python
4. ThinkPython: The way of the program
5. Variables, Booleans and None
6. Using functions
7. Setting up an editor
8. If, else and elif
9. Handy stuff with strings
10. Lists and tuples

16. What is true?
17. Files
18. Modules
19. Exceptions
20. Classes
21. Docstrings

Advanced

If you want to learn more advanced techniques, you can also read this section. Most of the techniques explained here are great when you're working on a large project, and your code would be really repetitive without these things.

You can experient with these things freely, but please don't use these techniques just because you know how to use them. Prefer the simple techniques from the Basics part instead when possible. Simple is better than complex.

1. Handy data types
2. Advanced stuff with functions
3. Magic methods
4. Iterables, iterators and generators

Frequently asked questions

How can I thank you for writing and sharing this tutorial?

You can star this tutorial. Starring is free for you, but it tells me and other people that you like this tutorial.

Go here if you aren't here already and click the "Star" button in the top right corner. You will be asked to create a GitHub account if you don't already have one.

How can I read this tutorial without an Internet connection?

1. Go here if you aren't here already.

2. Click the big green "Clone or download" button in the top right of the page, then click "Download ZIP".

   

3. Extract the ZIP and open it. Unfortunately I don't have any more specific instructions because how exactly this is done depends on which operating system you run.

4. Run make-html.py and follow the instructions.

If you have git and you know how to use it, you can also clone the repository instead of downloading a zip and extracting it. An advantage with doing it this way is that you don't need to download the whole tutorial again to get the latest version of it, all you need to do is to pull with git and run make-html.py again.
