Capture and compare stdout in python unit tests

A recent fan of TDD, I set out to write tests for whatever comes my way. And there was one feature where the code would print messages to the console. Now - I had tests written for the API but I could not get my head around ways to capture these messages in my unittests.
After some searching and some stroke of genius, here's how I accomplished capturing stdout.

On working remote

The last company I worked for, did have an office space, but the code was all on Github, infra on AWS, we tracked issues over Asana and more or less each person had at least one project they could call "their own" (I had a bunch of them ;-)). This worked pretty well. And it gave me a feeling that working remote would not be very different from this. So when we started working on our own startup, we started with working from our homes.
