How to manage and communicate with multiple IPython/Jupyter kernels from a Python script?

Question

I want to mimic the functionality of a notebook server, and instead coordinate the creation/management of different IPython/Jupyter kernels from a central body of logic (i.e

A KernelManager deals with starting and stopping a single kernel, and there's a MultiKernelManager to co-ordinate more than one.

• http://ipython.org/ipython-doc/3/api/generated/IPython.kernel.multikernelmanager.html

Then you can use the .client() method to get a KernelClient instance which handles communications with a kernel:

For details of how you communicate with a kernel, see the message spec docs. Some of this is abstracted away by KernelClient, but you'll probably need to know some of it.
