def parse_filename(fname):
"""Parse a notebook filename.
This function takes a notebook filename and returns the notebook
format (json/py) and the notebook name. This logic can be
summarized as follows:
* notebook.ipynb -> (notebook.ipynb, notebook, json)
* notebook.json -> (notebook.json, notebook, json)
* notebook.py -> (notebook.py, notebook, py)
* notebook -> (notebook.ipynb, notebook, json)
Parameters
----------
fname : unicode
The notebook filename. The filename can use a specific filename
extention (.ipynb, .json, .py) or none, in which case .ipynb will
be assumed.
Returns
-------
(fname, name, format) : (unicode, unicode, unicode)
The filename, notebook name and format.
