Run

<code>!pip install ipynb</code>

and then import the other notebook as

<code>from ipynb.fs.full.&lt;notebook_name&gt; import *</code>

or

<code>from ipynb.fs.full.&lt;notebook_name&gt; import &lt;function_name&gt;</code>

Make sure that all the notebooks are in the same directory.

Edit 1: You can see the official documentation here - <a href="https://ipynb.readthedocs.io/en/stable/" rel="noreferrer">https://ipynb.readthedocs.io/en/stable/</a>

Also, if you would like to import only class &amp; function definitions from a notebook (and not the top level statements), you can use <code>ipynb.fs.defs</code> instead of <code>ipynb.fs.full</code>. Full uppercase variable assignment will get evaluated as well.

The issue is that a notebooks is not a plain python file. The steps to import the <code>.ipynb</code> file are outlined in the following: <a href="http://nbviewer.jupyter.org/github/jupyter/notebook/blob/master/docs/source/examples/Notebook/Importing%20Notebooks.ipynb" rel="nofollow">Importing notebook</a>

I am pasting the code, so if you need it...you can just do a quick copy and paste. Notice that at the end I have the <code>import primes</code> statement. You'll have to change that of course. The name of my file is <code>primes.ipynb</code>. From this point on you can use the content inside that file as you would do regularly.

Wish there was a simpler method, but this is straight from the docs. 
Note: I am using jupyter not ipython.

There is no problem at all using Jupyter with existing or new Python .py modules. With Jupyter running, simply fire up Spyder (or any editor of your choice) to build / modify your module class definitions in a .py file, and then just import the modules as needed into Jupyter.

One thing that makes this really seamless is using the autoreload magic extension. You can see documentation for autoreload here:

<a href="http://ipython.readthedocs.io/en/stable/config/extensions/autoreload.html" rel="nofollow">http://ipython.readthedocs.io/en/stable/config/extensions/autoreload.html</a>

Here is the code to automatically reload the module any time it has been modified:

<pre><code># autoreload sets up auto reloading of modified .py modules
import autoreload
%load_ext autoreload
%autoreload 2
</code></pre>

Note that I tried the code mentioned in a prior reply to simulate loading .ipynb files as modules, and got it to work, but it chokes when you make changes to the .ipynb file. It looks like you need to restart the Jupyter development environment in order to reload the .ipynb 'module', which was not acceptable to me since I am making lots of changes to my code.

Please make sure that you also add a <code>__init__.py</code> file in the package where all your other .ipynb files are located.

This is in addition to the nbviewer link that <code>minrk</code> and <code>syi</code> provided above.

I also had some similar problem and then I wrote the solution as well as a link to my public google drive folder which has a working example :)

Hope this will help others as well.
Thanks all!

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.

The only workaround I see is converting my *.ipynb files into *.py files, which then can be imported into my notebook. Having one file hold everything in a project is a bit weird, especially if I want to really push for code-reuse (isn't that a core tenet of python?).

Am I missing something? Is this not a supported use case of ipython notebooks? Is there another solution I can be using for this import of an ipynb file into another notebook? I'd love to continue to use ipynb, but it's really messing up my workflow right now :(

ipynb import another ipynb file

Python

交互式Python (ipython)简直令人惊叹，尤其是当你在飞行中拼凑东西的时候……并且以一种很容易返回的方式来做。然而，有趣的是拥有多个ipython笔记本(ipynb文件)的用例。显然，似乎笔记本电脑不应该与其他笔记本电脑有关系，这是有道理的，除非我喜欢导入其他ipynb文件。我看到的唯一解决办法是将*.ipynb文件转换为*.py文件，然后可以将其导入到我的笔记本中。让一个文件保存项目中
