Free course on Kaggle Learn
Kaggle Learn's Python course is a free, fast-paced introduction to Python covering syntax, functions, data structures, and libraries in about 5 hours. All lessons run in Kaggle's browser notebooks, so no setup needed. After finishing, you can write Python scripts and understand the language basics. This course is shorter and more focused than full Python courses, making it ideal for learners who want a quick start. The main limitation: it's introductory only. After this, you need a specialized course (data science, web dev, etc.) to go deeper.
Python is the most popular programming language for data science and machine learning, used by 54.8% of professional developers (source: Stack Overflow Developer Survey 2025).
