How to start learning Python

They are free and divided into basics, applications, and data science. Within each direction, the articles are sorted by increasing complexity: from simple to tricky.

How to learn Python on your own and for free

How do you learn Python using our materials:

  • Read articles.
  • Watch the video.
  • Repeat after the teacher or author.
  • Google if something doesn’t work at all.
  • Type the word “Python” into Telegram and join the best chats where experienced Pythonists can answer any of your questions – if they want.

Allocate 1-2 hours daily for classes so that knowledge does not have time to disappear (according to the forgetting curve ), and try to stay at this pace for three weeks – they say a habit is developed during this period.

Don’t be afraid of mistakes. There will be many of them – both in the learning process and when you become a real programmer. Treat mistakes as reasons to get depressed and learn something new. Your learning cycle should look something like this:

  • Try.
  • Error.
  • Google, chat, or help a friend.
  • Bug fix.
  • GO TO item 1.

Python: programming language basics for beginners

With the help of our Python Tutorial, you will learn the language at a basic level: installing an interpreter, language syntax, importing libraries, basic data types, and operations on them. This is enough to create complex and useful programs and become a novice developer.


You can program in Python on your computer by downloading and installing the distribution kit (we recommend the Anaconda package or the PyCharm development environment ) or in the browser using special services (for example, Google Colab ).

  • How to run Python on Linux, Windows, and macOS
  • How to use the Google Colab service
  • PyCharm: how to install and use it

Basic Syntax

The path of a Pythonist begins with basic operators, the basic syntax of the language, and the installation of libraries. To learn Python from scratch, we recommend starting with these materials:

  • Dollar exchange rate chart in Anaconda. Let’s install the Anaconda distribution, learn the syntax, and draw a dollar rate graph.
  • Data Types in Python. Now that you’ve got to know the language, it’s time to learn what data types are and what they are in Python.
  • Word Cloud in Python. Let’s draw a cloud of the most frequent words from the Wikipedia page directly in the browser using Google Colab.
  • Installing the library in Python. The main methods are manual installation using easy installation and the most popular one using the PIP utility.
  • Webinar ” Drawing a tree with Python. ” Let’s learn a little more commands and functions, deal with cycles and conditions, and import the library for drawing.


Lists are the most popular data type you’ll be working with most of your time, so it’s worth learning. Beginning Python developers should know the following:

  • Lists in Python. We start, of course, with the basics and understand how lists work.
  • Removing an element from a list in Python Let’s learn about four ways to remove an element from a list.
  • The append() and extend() methods in Python. Let’s determine the differences between the two methods of adding elements to the list.
  • Convert the list to a string. It is also useful to know how different data types can be converted into others – for example, lists into strings.
  • 11 questions about lists. If, at the interview, they start chasing you on this type of data, you will not get lost.


Postmodernists said: the world as a text and the text as the world. This is especially true in programming – including in Python. Therefore, it is important to be able to work with strings.

  • Formatted Strings with Examples. We analyze a convenient and visual way to display strings.
  • Concatenation of strings. They must always be combined, so it’s time to find the most effective methods.
  • Regular Expressions. They are useful when you need to parse and process strings.

Tools and chips

A good programmer is a curious programmer. Knowledge of chips and non-obvious nuances of the language is one of the signs of a good programmer, even a beginner.

  • Generators in Python: what are they, and why are they needed? One of the characteristic features of Python is the creation of complex objects in literally 1-2 lines. This will help generators.
  • 15 Short Python Programs. Short and clear programs allow you to understand the language better.
  • Collections library. Tools that you will constantly use in development.
  • Vim as an IDE for Python. If you want to become a hardcore developer, learn Vim instead. It looks cool, works fast, and has many cool features.

Advanced Features

Python is lenient towards beginners – because it allows you to solve some problems casually, sacrificing code cleanliness in exchange for development speed. But this does not mean that there is no correct and beautiful solution.

  • Correct String Concatenation in Python. Yes, you can concatenate strings with a + sign, but there are better ways.
  • Decorators: what to answer in an interview. A function that modifies (decorates) another function. Sounds promising!
  • Random Numbers in Python. There are no accidents, especially in Python. Or…
  • Refactoring code in Python. Most of the work of a programmer is not writing new code but reading and reworking (refactoring) the old one. Let’s do it right!
  • Recursive Functions. Functions can call themselves. This is called “recursion.” We understand how it works and where it can be useful.

Object Oriented Programming

One day you will see your programs get bigger and more difficult to maintain. Then you’ll think about how to fix it. The answer is simple – use OOP.

  • OOP in Python. Probably the most important topic of all. You will learn what objects and classes are and how to write concise code.
  • Create a “Snake” on Pygame. Consolidate your knowledge and rewrite the game code according to OOP principles. We are sure that you will succeed.

To learn more about OOP, we also recommend reading our articles on the main concepts of this paradigm:

  • Classes and Objects. The basic elements of all OOP, from which everything else is built.
  • Features of working with objects. Nuances when working with objects.
  • Encapsulation and access modifiers. Access to methods inside objects sometimes needs to be protected; this is done using encapsulation and access modifiers.
  • Overloading Methods and Operators. A trick in object-oriented programming that allows you to define multiple methods with the same name.
  • Polymorphism. Learn more about overloading at a conceptual level.
  • Inheritance and some more polymorphism. We get rid of duplicate code and make projects even more concise.
  • Abstract Classes and Interfaces. In the case of OOP, we move away from all material things and think in abstract ideas – or abstract classes and interfaces.

Python: writing applications

The best way of learning than repeated repetition after the teacher has yet to be invented. Repeat all the steps after our teachers, and you will learn how to work in PyCharm, crack passwords and create real messengers.
