Kaggle is best known for data science competitions, but it also has Kaggle Learn: a set of short, free, hands-on lessons on topics like Python, data analysis and machine learning.

Why beginners like it

• Each lesson is short, so you can finish one in an evening.
• You write code in the browser, so nothing needs installing.
• Exercises give you instant feedback.

A simple path to follow

1. Start with the Python lessons if you are new to coding.
2. Move on to data handling and basic machine learning.
3. Try a beginner dataset and share your notebook as a portfolio piece.

Course lists and certificates change over time, so check Kaggle’s site for what is available now. It is a good, no-cost way to test whether you enjoy working with data before you pay for anything.
