How to display and raise warnings in release pipeline for Azure devops

Question

I'm running a Python script in my Azure DevOps Release Pipeline that eventually logs warnings or errors based on my custom logger package.

So I can see that it's operating well from my std output of the Azuredevops.

However, I'm curious if it's feasible to show the number of errors or warnings on the badge, similar to the example below.

You should, in my opinion, use command line logging.

But the point is, how can I use Python to track the problems or warnings from AzDevops standard output?

We welcome any ideas and suggestions.
