How to document Python function parameters with sphinx-apidoc?

Adding this answer to consolidate options:

pydoc is basic with no special formatting

epydoc uses the format '@param var:'

Doxygen is oriented for a larger range of languages

Sphinx uses the format ':param type var:'. Also see more examples. This was used to create the Python 3.5 documentation.

Typically "function variables" are called parameters ;).

It's documented here: http://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#signatures

And the answer is :param ________

EDIT Disclaimer: I've never used or heard of sphinx... This post is mostly a "what words to search for." Hope it helped.
