Publishing DataLineagePy to PyPI

Complete guide for publishing your DataLineagePy package to PyPI (Python Package Index).

🎯 Prerequisites

✅ PyPI Account Created - You mentioned you already have this!
✅ Project Ready - Code, documentation, and tests complete
✅ Version Finalized - Ready for v1.0.0 release

📦 Pre-Publication Checklist

1. Verify Project Structure

├── docs/               # Documentation ✅
├── examples/           # Example code ✅
├── tests/              # Test suite ✅
├── README.md           # Project description ✅
├── CHANGELOG.md        # Version history ✅

├── MANIFEST.in         # Package inclusion rules ✅
├── requirements.txt    # Dependencies ✅
└── .gitignore         # Git ignore rules ✅

2. Version and Metadata Check

  • Package Name: datalineagepy ✅
  • Version: 3.0.3 ✅
  • Author: Arbaz Nazir ✅
  • Email: arbaznazir4@gmail.com ✅
  • License: MIT ✅

3. Clean Build Environment

# Remove any old build artifacts
Remove-Item -Recurse -Force build, dist, *.egg-info -ErrorAction SilentlyContinue

🛠️ PyPI Publishing Steps

Step 1: Install Publishing Tools

pip install --upgrade build twine

Step 2: Build the Package

# Build source distribution and wheel
python -m build

# This creates:
# dist/datalineagepy-1.0.0.tar.gz (source)
# dist/datalineagepy-1.0.0-py3-none-any.whl (wheel)

Step 3: Verify the Build

# Check what files are included
tar -tzf dist/datalineagepy-1.0.0.tar.gz

# Verify package metadata
twine check dist/*

Step 4: Test Upload (TestPyPI First)

# Upload to TestPyPI first (recommended)
twine upload --repository testpypi dist/*

# When prompted, enter your PyPI credentials
# Username: your_pypi_username
# Password: your_pypi_password (or API token)

Step 5: Test Installation from TestPyPI

# Install from TestPyPI to verify
pip install --index-url https://test.pypi.org/simple/ datalineagepy

# Test basic import
python -c "from lineagepy import LineageTracker; print('Success!')"

Step 6: Upload to Production PyPI

# Upload to production PyPI
twine upload dist/*

# Enter your PyPI credentials when prompted

🔐 API Token Setup (Recommended)

Instead of username/password, use API tokens for security:

1. Create PyPI API Token

  1. Go to https://pypi.org/manage/account/
  2. Scroll to "API tokens" section
  3. Click "Add API token"
  4. Set scope to "Entire account" or specific project
  5. Copy the token (starts with pypi-)

2. Configure Token

# Create .pypirc file (Windows: %USERPROFILE%\.pypirc)
# Linux/Mac: ~/.pypirc

[distutils]
index-servers =
    pypi
    testpypi

[pypi]
username = __token__
password = pypi-YOUR_TOKEN_HERE

[testpypi]
repository = https://test.pypi.org/legacy/
username = __token__
password = pypi-YOUR_TESTPYPI_TOKEN_HERE

🚀 Complete Publishing Command Sequence

# 1. Clean previous builds
Remove-Item -Recurse -Force build, dist, *.egg-info -ErrorAction SilentlyContinue

# 2. Build package
python -m build

# 3. Check package
twine check dist/*

# 4. Upload to TestPyPI (optional but recommended)
twine upload --repository testpypi dist/*

# 5. Test install from TestPyPI
pip install --index-url https://test.pypi.org/simple/ datalineagepy

# 6. Upload to production PyPI
twine upload dist/*

✅ Post-Publication Verification

1. Check PyPI Page

Visit: https://pypi.org/project/datalineagepy/

Verify:

  • ✅ Package description displays correctly
  • ✅ README renders properly
  • ✅ Links work (GitHub, documentation)
  • ✅ Version and metadata are correct

2. Test Installation

# Test fresh installation
pip install datalineagepy

# Test import
python -c "from lineagepy import LineageTracker, DataFrameWrapper; print('✅ Package works!')"

# Test example
python -c "
import pandas as pd
from lineagepy import LineageTracker, DataFrameWrapper

tracker = LineageTracker()
df = DataFrameWrapper(pd.DataFrame({'a': [1,2,3]}), tracker, 'test')
result = df['a'].sum()
print('✅ Basic functionality works!')
"

3. Test Documentation Links

  • ✅ GitHub repository accessible
  • ✅ Documentation displays correctly
  • ✅ Examples run successfully

📊 Package Statistics & Monitoring

After publishing, monitor your package:

PyPI Statistics

GitHub Integration

  • Releases: Create GitHub releases to match PyPI versions
  • Tags: Tag releases in Git for version tracking
  • Issues: Monitor for user feedback and bug reports

🔄 Future Updates

Version Updates

# Update version in pyproject.toml
# Update CHANGELOG.md with new features
# Build and upload new version
python -m build
twine upload dist/*

Best Practices

  • Semantic Versioning: 1.0.0 → 1.0.1 (patch) → 1.1.0 (minor) → 2.0.0 (major)
  • Changelog: Always update CHANGELOG.md
  • Testing: Run full test suite before publishing
  • Documentation: Update docs for new features

🎉 Success Metrics

Your package will be ready when users can:

# Simple installation
pip install datalineagepy

# Immediate usage
from lineagepy import LineageTracker, DataFrameWrapper

🚨 Troubleshooting

Common Issues

Build Errors

# If build fails, check:
python -m pip install --upgrade setuptools wheel build

Upload Errors

# If upload fails with authentication:
# 1. Verify credentials in .pypirc
# 2. Use API tokens instead of passwords
# 3. Check token has correct permissions

Version Conflicts

# If version already exists:
# 1. Update version in pyproject.toml
# 2. Rebuild package
# 3. Upload new version
