what is ipynb
1. Interactive Python (ipython) is simply amazing, especially as you are piecing things together on the fly... and does it in such a way that it is easy to go back. However, what seems to be interesting is the use-case of having multiple ipython notebooks (ipynb files). It apparently seems like a notebook is NOT supposed to have a relationship with other notebooks, which makes sense, except that I would love to import other ipynb files.
