I am reading Python Data Science Handbook by Jake VanderPlas recently. This book is shared by the author on his website, and in the form of Jupyter Notebook on github. While reading the book, I installed Jupyter Notebook on my Fedora system and tested out the examples. This process is amazing! I can see why Jupyter Notebook is widely utilized. My notes on NumPy is uploaded here to test out the jupyter nbconvert --to markdown function. With Jupyter Notebook, I can get my hands on many projects, such as tutorials and example codes. Great appreciation to the author and many other contributors!
