Useful in class and for personal use
Format: Paperback
We are learning python in my class and this book is so helpful to practice outside of class. I had started using it before class started because I didn’t know we would be learning python I just bought it because python is a popular programming language and I should learn it and it’s very simple to follow. The digital assets help u download the necessary tools used in the book. I do find the code to be a little confusing because I’m used to SQL and R. Python is a little different but the book makes it easy to learn and has you implementing what you learned into a project so it’s very useful. Get this book!
