Execute code blocks in Sphinx and display the output

sphinx-exec-code

A Sphinx extension to run python code in the documentation

About

Sphinx-exec-code allows execution of any python code during the documentation build. It's also possible to display the output of the code execution.

With this extension it's easy to ensure that the provided code samples are always working. Additionally, it's possible to show the output of the documented code.

Each code snippet runs in a fresh interpreter so changes to not leak between executions.
