In this Google Photos API and Python tutorial series, I will be covering how to use the Google Photos API in Python.

The Photos API has 3 main resources. You can think each resource as a class for a specific purpose. And for each resource, I will make an individual video for each of them.

I will guide you thorugh every single step to the point you can start hit the ground running.
