ipython-notebook

If I have several IPython notebooks running on the same server. Is there any way to share data between them? For example, importing a variable from another notebook? Thanks! This works for me : The %store command lets you pass variables between two different notebooks. data = 'this is the string I want to pass to different notebook' %store data Now, in a new notebook… %store -r data print(data) this is the string I want to pass to different notebook I've successfully tested with sklearn dataset : from sklearn import datasets dataset = datasets.load_iris() %store dataset in notebook to read

Is there a way to selectively hide one specific input or output cell in IPython notebook? I could only find the below code to show / hide all input cells. http://blog.nextgenetics.net/?e=102 But what if I only want to hide the first input cell of a notebook? This is now built into nbconvert ( as of 5.3.0 ) using tags. Here's an example removing a specific cell from the output. Using this notebook . The example has three cells: a markdown cell, a code cell that will be hidden, and a code cell that will not be hidden. Add the remove_cell tag to any cells you want to hide using the tag editor

I would like my default display for IPython notebook code cells to include line numbers. I learned from Showing line numbers in IPython/Jupyter Notebooks that I can toggle this with ctrl-M L, which is great, but manual. In order to include line numbers by default, I would need to add something to my ipython_notebook_config.py file. Unless I've missed something, there is not an explanation of how to do this in the documentation. In your custom.js file (location depends on your OS) put IPython.Cell.options_default.cm_config.lineNumbers = true; If you can't find custom.js, you can just search for

I often run long-running cells in my IPython notebook. I'd like the notebook to automatically beep or play a sound when the cell is finished executing. Is there some way to do this in iPython notebook, or maybe some command I can put at the end of a cell that will automatically play a sound? I'm using Chrome if that makes any difference. Waylon Flinn TL;DR At the top of your notebook from IPython.display import Audio sound_file = './sound/beep.wav' sound_file should point to a file on your computer, or accessible from the internet. Then later, at the end of the long-running cell <code that

I am using IPython and want to run functions from one notebook from another (without cutting and pasting them between different notebooks). Is this possible and reasonably easy to do? You can connect with a qtconsole to the same kernel. Just supply this at startup: ipython qtconsole --existing kernel-0300435c-3d07-4bb6-abda-8952e663ddb7.json Look at the output after starting the notebook for the long string. Matt Starting your notebook server with: ipython notebook --script will save the notebooks ( .ipynb ) as Python scripts ( .py ) as well, and you will be able to import them. Or have a look

I find that developing functions in IPython notebook allows me to work quickly. When I'm happy with the results I copy-paste to a file. The autoindent is 4 spaces, but the coding style for indentation at my company is 2 spaces. How do I change the autoindent to 2 spaces? Jakob Based on this question and the options found here : In your custom.js file (location depends on your OS) put IPython.Cell.options_default.cm_config.indentUnit = 2; On my machine the file is located in ~/.ipython/profile_default/static/custom Update: In IPython 3 the plain call does not work any more, thus it is required
