added python examples to swagger docs

[matthewberry]

We'd like OED users to have access to sample python code for calling the API.

There are currently nice examples in the README file, but the README file is written for people who are cloning this repo and running it locally. We expect many OED users would rather use the hosted API.

This PR therefore adds python examples to the swagger page. Screenshots are below.

Ideally we'd DRY this up, but we need a very quick solution for this week.

BTW, the purple code is a swagger default that's something of a hassle to override.

Thanks @matthewberry! No worries about the purple code hahaha ... the examples look similar to examples for REST APIs/SOAP APIs I've used before for BRENDA and other DBs so I think this type of example will be quite useful for computational biologists.
