Complete data science course by Frank Andrade (The PyCoach), on freeCodeCamp. You learn Python basics, Pandas and NumPy, data cleaning, filtering, reshaping, merging, regular expressions, data visualisation and machine learning with scikit-learn — with 4 real projects (web scraping, visualisations, data cleaning, text classification). About 17 hours, one video, embedded from YouTube, not re-uploaded. The video is locked and is shown only after you buy the course and the admin confirms your payment — it then appears in My Downloads and on your confirmed order page. Please provide screenshot after payment.
