问题 The documentation at http://ipython.org/ipython-doc/stable/interactive/notebook.html says You can provide a conceptual structure for your computational document as a whole using different levels of headings; there are 6 levels available, from level 1 (top level) down to level 6 (paragraph).

问题 I just started IPython Notebook, and I tried to use "Save" to save my progress. However, instead of saving the *.ipynb in my current working directory, it is saved in my python/Scripts folder.

阅读更多关于 IPython Notebook output cell is truncating contents of my list

I have a long list (about 4000 items) whose content is suppressed when I try to display it in an ipython notebook output cell.

All I could do up until now is: import pandas as pd data = pd.ExcelFile("*File Name*") Now I know that the step got executed successfully, but I want to know how i can parse the excel file that has been read so that I can understand how the data in the excel maps to the data in the variable data.
