In part 1 of the Google Tasks API with Python tutorial, I will 1) give a quick overview of the API, 2) show you how to enable the API, and 3) create a Google Tasks API service instance so you can start using the API.

Google Tasks is a very popular To-Do app created by Google. Using the Google Tasks API, we can use Python or any other programming languages to search, read, create, and update Google tasks. As someone who has experience using most of the Google APIs, Google Tasks API is probably one of the easiest APIs to use.
