Have jupyter notebooks save also as html and python scripts

jupyter_notebook_config.py

# Ref: https://www.svds.com/jupyter-notebook-best-practices-for-data-science/

# Jupyter 4.x is now out! 

# Further, config files are stored in ~/.jupyter by default. This directory is the JUPYTER_CONFIG_DIR environment variable. I’m going to first describe the above with the default config, and go into the complicated way of doing with Jupyter’s version of profiles.

# The default config file is found at: ~/.jupyter/jupyter_notebook_config.py

# If you don’t have this file, run: jupyter notebook --generate-config to create this file.

# Add the following text to the top of the file:

c = get_config()
### If you want to auto-save .html and .py versions of your notebook:
