Introduction to Git and GitHub for Full Stack Python Developers
Git and GitHub are essential tools for modern full-stack development. They enable you to track code changes, collaborate with teams, integrate CI/CD pipelines, and manage deployments. As a Python developer working with frameworks like Flask, Django, FastAPI, and frontend tools like React/Vue, Git/GitHub become central to your daily workflow.
1. What is Git?
Git is a distributed version control system (VCS) that lets you:
Track changes in your code
Revert to earlier versions
Work on multiple features simultaneously
Collaborate without overwriting each other’s work
Maintain clean development workflows
Core Git concepts
Repository (repo): A project directory tracked by Git.
Commit: A snapshot of your code at a point in time.
Branch: A parallel line of development.
Merge: Combine changes from one branch into another.
Remote: A Git repo stored on a server (e.g., GitHub).
Staging area (index): Where changes go before committing.
2. What is GitHub?
GitHub is a cloud platform for hosting Git repositories plus tools for:
Collaboration (pull requests, issues, discussions)
Project management (Projects, Milestones)
Automation (GitHub Actions for CI/CD)
Security (dependabot, secret scanning)
Deployment (GitHub Pages, GitHub Packages)
For full-stack Python developers, GitHub is often the “hub” for your entire workflow—from code to deployment.
3. Setting Up Git for Python Development
Install Git
Windows: Download installer
macOS: Built-in or via Homebrew
Linux: sudo apt install git (Debian/Ubuntu)
Configure your identity
git config --global user.name "Your Name"
git config --global user.email "your@email.com"
Initialize a new repo
git init
Typical project structure
my_project/
├── backend/
│ ├── app.py
│ ├── requirements.txt
│ └── ...
├── frontend/
│ ├── package.json
│ ├── src/
│ └── ...
├── .gitignore
└── README.md
.gitignore for Python developers
Common entries:
__pycache__/
*.pyc
.env
venv/
.env
node_modules/
4. Working with Git: The Basic Workflow
A. Checking status
git status
B. Staging and committing
git add .
git commit -m "Add initial FastAPI backend"
C. Branching (important for full-stack teams)
git checkout -b feature/user-auth
D. Merging
git checkout main
git merge feature/user-auth
E. Handling conflicts
If two people edit the same lines, Git prompts you to manually resolve conflicts in your editor.
5. Connecting Git to GitHub
Create a remote repository
On GitHub → “New Repository”
Link local repo to GitHub
git remote add origin https://github.com/username/project.git
git push -u origin main
Cloning a repo
git clone https://github.com/username/project.git
6. Collaboration Using GitHub
Pull Requests (PRs)
A PR is how you propose changes. Typical PR flow:
Create a feature branch locally
Push it to GitHub
Open a PR
Request review
Make fixes
Merge into main
Issues
Used for:
Bug reports
Feature requests
Documentation tasks
Projects & Kanban boards
Track work in agile workflows.
7. Full-Stack Python Workflows with GitHub
A. Backend (Django, Flask, FastAPI)
GitHub Actions can:
Run tests
Install dependencies
Check formatting (Black, Ruff, Flake8)
Build and publish Docker images
Example GitHub Action for Python tests
name: Python CI
on: [push, pull_request]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
with:
python-version: "3.12"
- run: pip install -r backend/requirements.txt
- run: pytest backend/tests
B. Frontend (React, Vue, Svelte)
GitHub Actions can:
Install npm packages
Run unit tests
Build production bundles
Deploy to GitHub Pages, Azure, AWS, etc.
C. DevOps / Deployment
GitHub integrates with:
Docker Hub
AWS Elastic Beanstalk
Azure Web Apps
Fly.io
Railway
Kubernetes clusters
You automate CI/CD pipelines to deploy each merge to staging/production.
8. Advanced Git Techniques for Full-Stack Developers
Rebasing
Keeps commit history clean:
git rebase main
Stashing
Temporarily store changes:
git stash
Cherry-picking
Apply a specific commit:
git cherry-pick <hash>
Tags
Used for versioning:
git tag v1.0
9. Best Practices for Full Stack Python Teams
Use feature branches for every task.
Keep main branch stable and production-ready.
Write clear commit messages.
Protect branches with GitHub rules (e.g., require PR review).
Use code formatters (Black, Prettier).
Use linters (Ruff, ESLint).
Automate tests with GitHub Actions.
Document everything in the README.
Avoid committing secrets—use environment variables and secret management.
10. Summary
Git + GitHub provide the backbone of a full-stack Python workflow:
Git helps you manage versions, branches, and collaboration.
GitHub adds hosting, CI/CD, automation, reviews, and project management.
Together, they empower you to build reliable backend APIs, frontend UIs, and deploy full-stack applications efficiently.
