A professional Python project template that always uses portable Python - never relies on system installations.

• 🎯 Always Portable - Consistent Python environment everywhere
• 📦 Self-Contained - No dependency on system Python
• 🔄 Reproducible - Same exact Python version every time
• 🚀 Distributable - Package includes everything needed

# 1. Clone or use this template
git clone https://github.com/yourusername/your-project
cd your-project

# 2. Run setup (downloads Python 3.13.9 first time, ~2 minutes)
./setup.sh

# 3. Activate and run
source .venv/bin/activate
python src/main.py

That's it! No system Python needed.

# Setup (first time downloads Python, subsequent runs reuse it)
./setup.sh

# If something breaks, clean rebuild
./setup.sh --force-clean

# Add a dependency
# 1. Edit pyproject.toml
# 2. Then:
poetry lock
poetry sync

1. Downloads pre-built Python 3.13.9 from python-build-standalone
2. Installs to .python/ directory
3. Creates virtual environment in .venv/
4. Installs dependencies with poetry

1. Finds existing .python/ installation
2. Reuses it (no download needed!)
3. Creates fresh .venv/
4. Installs dependencies

1. Deletes .python/, .venv/, poetry.lock
2. Downloads Python 3.13.9 again
3. Fresh installation

• .python/ : ~80 MB (one-time)
• .venv/ : ~50 MB (varies by dependencies)
• Total: ~150 MB uncompressed
• Package: ~50 MB compressed

Small price for complete portability!

# Day 1: Setup
./setup.sh
source .venv/bin/activate

# Daily development
python src/main.py
pytest

# Add dependencies
# Edit pyproject.toml, then:
poetry lock && poetry sync

# If weird issues
./setup.sh --force-clean

# 1. Ensure clean build
./setup.sh --force-clean

# 2. Test your app
source .venv/bin/activate
python src/main.py

Edit setup.sh:

PYTHON_VERSION="3.14.*"  # Or any version

Available versions: https://github.com/indygreg/python-build-standalone/releases

# Virtual environment issues
rm -rf .venv/ && ./setup.sh

# Complete fresh start
./setup.sh --force-clean

# Check what you have
.python/bin/python3 --version
source .venv/bin/activate && python --version

Portable Python is OS and architecture specific:

• ✅ macOS x86_64 → macOS x86_64
• ✅ macOS arm64 (M1/M2/M3) → macOS arm64
• ✅ Linux x86_64 → Linux x86_64
• ✅ Linux aarch64 → Linux aarch64
• ❌ macOS → Linux (use Docker)
• ❌ x86_64 → arm64 (use Docker)
• ❌ Windows (use WSL or Docker)

This project follows Conventional Commits for clear and structured commit history.

Format:
