Git + Python
Automate Git from Python — diffs, hooks, release tags, and repo housekeeping.
Fetch Pull Rebase Workflow Script in Python
A Python script that automates the git fetch, checkout, and pull with rebase workflow using subprocess.
import subprocess
import sys
def run_git_command(args: list[str]) -> str:
"""Run a git command and return its stdout, or raise on failure."""
result = subprocess.run(
["git", *args],
capture_output=True,
text=True,
check=False,
)

prin…How to Create a Git Branch if it Doesn't Exist in Python
Utility script that checks if a Git branch exists locally and either creates it or checks it out, with error handling.
import subprocess
import sys
def ensure_branch(branch_name):
"""Create a Git branch if it doesn't exist, otherwise checkout it."""
try:
# Check if the branch exists locally
result = subprocess.run(
["git", "branch", "--list", branch_name],

…How to Mock git sparse-checkout Paths in Python
Simulates git sparse-checkout configuration by writing desired paths to the sparse-checkout file without running git commands.
import subprocess
from pathlib import Path
import tempfile
def configure_sparse_checkout(repo_dir: Path, paths: list[str]) -> list[str]:
"""Simulate sparse checkout configuration by returning the paths that would be set."""
sparse_checkout_file = repo_dir / ".git" / "info" / "sparse-checkout"

This code shows how to use unittest.mock.patch with mock_open to test a function that checks if a Git patch can be reverse-applied by reading file content.

def apply_reverse_check(file_path, expected_patch):
"""
Check if a patch can be reverse-applied by comparing file content
with the expected patch's reverse result.
