In this video, I demonstrated jupyter notebook extensions that will make R and Python data science codes efficient.
To install nb extension: run the following two codes in your command line
pip install jupyter_contrib_nbextensions
To make it dark mode: run the following code in the command line before running jupyter notebook
pip install jupyterthemes #install jupyter themes
jt -t onedork -T -N #dark mode
Now fire jupyter notebook, go to nb extensions and activate "Hinterland". Then, open or create your new script. Autocompletion and dark mode are activated. Enjoy Jupyter Notebook
