GitPython
is a python api for your git repos, it can be quite handy when you
need to work with git from python.
Use Case
I recently made myself a handy tool for making screenshots in python and it need to do a git commit and push from within the script. For this I reached for GitPython
.

Installation
GitPython
is a python library hosted on pypi that we will want to install
into our virtual environments using pip.
pip install GitPython
Create a Repo Object
Import Repo from the git library and create an instance of the Repo
object by giving it a path to the directory containing your .git
directory.
from git import Repo repo = Repo('~/git/waylonwalker.com/')
Two interfaces
from the docs
It provides abstractions of git objects for easy access of repository data,
and additionally allows you to access the git repository more directly using
either a pure python implementation, or the faster, but more resource
intensive git command implementation.
I only needed to use the more intensive but familar to me git command implementation to get me project off the ground. There is a good tutorial to get you started with their pure python implementation in their docs.
Status
Requesting the git status can be done as follows.
note I have prefixed my commands with >>> to distinguish between the command
I entered and the output.
>>> print(repo.git.status())
On branch main Your branch is ahead of 'origin/main' by 1 commit.
(use "git push" to publish your local commits)
Untracked files:
(use "git add <file>..." to include in what will be committed)
blog/
You can even pass in flags that you would pass into the cli.
>>> print(repo.git.status("-s"))
?? blog/
log
Example of using the log.
print(repo.git.log('--oneline', '--graph'))

Find Deleted Files
We can even do things like find all files that have been deleted and the hash they were deleted.
print(repo.git.log('--diff-filter', 'D', '--name-only', '--pretty=format:"%h"'))

My Experience
This library seemed pretty straightforward and predicatable once I realized there were two main implementations and that I would already be familar with the more intensive git command implementation.
