Get the current git hash in a Python script

by

No need to hack around getting data from the git command yourself. GitPython is a very nice way to do this and a lot of other git stuff. It even has “best effort” support for Windows.

After pip install gitpython you can do

import git
repo = git.Repo(search_parent_directories=True)
sha = repo.head.object.hexsha

Something to consider when using this library. The following is taken from gitpython.readthedocs.io

Leakage of System Resources

GitPython is not suited for long-running processes (like daemons) as it tends to leak system resources. It was written in a time where destructors (as implemented in the __del__ method) still ran deterministically.

In case you still want to use it in such a context, you will want to search the codebase for __del__ implementations and call these yourself when you see fit.

Another way assure proper cleanup of resources is to factor out GitPython into a separate process which can be dropped periodically
