Take a little time each day to review your cheat sheets and you will have it down in no time!
Cheat Sheet 1: DataCamp
This Scikit-Learn cheat sheet from DataCamp will kick start your data science project by introducing you to the basic concepts of machine learning algorithms successfully. This cheat sheet is for those who have already started to learn Python packages and for those who would like to take a quick look to get a first idea of the basics for total beginners!
Scikit Learn Cheat Sheet Pdf
Pros: This cheat sheet is rated ‘E’ for everyone!! Information is sectioned in blocks for easier reading
