The 5 Best Python Resources for Beginners to Advanced Programmers
Python is a good first language: its syntax is simple and reads almost like English. It is also widely used; Google, Netflix and Facebook all use Python.
There are many Python courses online, and it is easy to end up with one that is outdated or of low quality. I had this problem when I started learning to code. Now, as R&D Lead at Go Wombat, I can recommend five resources for learning Python and practising it.
“I’m Just Starting” – Beginner Level
CS50
CS50 is a free online introduction to computer science taught by Harvard University. It is a good way into programming and covers several languages: C, Python, SQL, HTML, CSS and JavaScript. It also teaches core concepts such as arrays and data structures. The current edition, CS50x 2026, includes a separate week on Artificial Intelligence; earlier editions also had lectures on Security and Ethics. I took the course after I had already started working as a developer, to fill gaps in my theoretical knowledge. It worked, and I recommend it to everybody.
A Byte of Python by Swaroop
A Byte of Python is a free book that teaches Python and how to write ‘Pythonic’ code. It gives a solid grounding in the language’s features. At Go Wombat it is required reading for every Junior Developer: I read it during my onboarding, and it helped me understand the language more deeply.
“I Know Something” – Intermediate Level
CheckiO
CheckiO is a set of coding games for beginners and advanced programmers. You solve puzzles in Python and improve your coding and logic along the way. I used it just before I applied for a junior position at Go Wombat. The game format works well for me, and I recommend it to every Python developer.
Learn X in Y Minutes
Learn X in Y Minutes is a quick reference for many languages, not just Python. I started out writing C++, and it helped me a lot to carry that knowledge over to Python.
“I Want More” – Advanced Level
Codewars
Codewars is a set of coding challenges at different difficulty levels. Working through the harder ones is a good way to sharpen your skills. It is community-driven: you can create challenges for others and pick up interesting ones they have written.
I still go back to all five from time to time.
