How to Schedule & Automatically Run Python Code!

In this video we learn various methods for how we can schedule and automatically run python code. We’ll start by looking at cronjobs & windows task scheduler and then we will walk through running tasks in the cloud using AWS Lambda & Cloudwatch. The ultimate goal of this video is to learn how we can automatically generate & send an email with an analytics report every day.

There are methods highlighted in this video that will work on Mac, Linux, & Windows.
