Start with DataCamp or Codecademy for hands-on, interactive practice with Python and SQL basics.

2. Build a statistics and ML foundation

Coursera's Machine Learning Specialization is a widely recommended next step once you're comfortable with the basics.

3. Go deeper with a structured program

For a more intensive, project-graded path, consider a Udacity Nanodegree or an edX MicroMasters.
