Suggest Automated DevOps Branch Building Workflow for Python

Bounty Points: 5

As a developer or tester
When I create a branch in my git repo
Then it should trigger an automated build process in the CI server
And it should give me feedback if the build has failed
or passed a previously failed build

Note-
The script should tag the repo.
Pull the earlier tag and increase the version of the artifact/package.

No files, tests, or CI entry points are named. Start by inspecting the repository and determining which CI server and package or artifact format are intended, then trace the existing versioning and tagging setup. Done means branch builds run automatically, report success or failure, recover from a previously failed build, tag the repository, and increment the artifact or package version.
