Welcome to my learning path!#
If you’ve reached this page, thank you for taking the time to read the content I’ve created while learning data science. I also hope you enjoy it as much as I did. Please feel free to extract the CSV files from My github repository from which I generated this book.
Furthermore, if you have any comments or suggestions, please don’t hesitate to share them with me via my Linkedin Profile.
