67 This function takes a notebook filename and returns the notebook 

68 format (json/py) and the notebook name. This logic can be 

69 summarized as follows: 

70 

71 * notebook.ipynb -> (notebook.ipynb, notebook, json) 

72 * notebook.json -> (notebook.json, notebook, json) 

73 * notebook.py -> (notebook.py, notebook, py) 

74 * notebook -> (notebook.ipynb, notebook, json) 

75 

76 Parameters 

77 ---------- 

78 fname : unicode 

79 The notebook filename. The filename can use a specific filename 

80 extention (.ipynb, .json, .py) or none, in which case .ipynb will 

81 be assumed. 

82 

83 Returns 

84 ------- 

85 (fname, name, format) : (unicode, unicode, unicode) 

86 The filename, notebook name and format.
