Git — Essential for Every Python Project

Initialize & basic workflow:

git init
git add .
git commit -m "Initial commit"
git push origin main

.gitignore for Python projects:

venv/
__pycache__/
*.pyc
.env
*.egg-info/
dist/
build/
.pytest_cache/
.mypy_cache/

Branching workflow:

git checkout -b feature/add-login   # create & switch
git add .
git commit -m "Add login feature"
git checkout main
git merge feature/add-login
git branch -d feature/add-login    # delete branch

Undoing mistakes:

git diff                    # see uncommitted changes
git checkout -- file.py    # discard file changes
git reset HEAD~1            # undo last commit (keep changes)
git revert HEAD             # undo last commit (new commit)

Commit message convention: Start with a verb: "Add login feature", "Fix null pointer bug", "Update README". Keep under 50 chars for the subject line.
