Using Command-Line Interface (CLI)

You can also directly execute Python code from the CLI without entering the interactive shell. Navigate to the root of your project and run:

python3 -c "from airports import airport_data; result = airport_data.get_airport_by_iata('MAA'); print(result)"

Replace 'MAA' with other codes as needed.

Testing

To test the library locally:

• Navigate to the root of the project:

cd path_to_airports-py

• Run the tests using:

python3 -m unittest discover tests -v

This command will discover and run all test files inside the tests directory and provide a detailed output.

Running the Project Locally

Prerequisites

• Python 3.6 or higher
• Git

Setup Instructions

• Clone the repository:

git clone https://github.com/aashishvanand/airports-py.git

• Change into the cloned directory:

cd airports-py

• Create a virtual environment (recommended):

python3 -m venv venv

• Activate the virtual environment:

# On macOS/Linux:
source venv/bin/activate

# On Windows:
venv\Scripts\activate

• Install development dependencies:

pip install --upgrade pip
pip install build twine pytest pytest-cov

• Install the package in development mode:

pip install -e .

• Generate the compressed data file (if needed):

# Generate airports.gz from airports.json
python scripts/generate_airports_gz.py

# Verify the data file
python scripts/generate_airports_gz.py --verify-only

Testing

• Run all tests:

python -m unittest discover tests -v

• Run tests with pytest (alternative):

python -m pytest tests/ -v

• Run tests with coverage:

python -m pytest tests/ -v --cov=airports --cov-report=term-missing

• Test basic functionality manually:

python -c "
from airports import airport_data
print('Testing IATA lookup:')
result = airport_data.get_airport_by_iata('LHR')
print(f'Found: {result[0][\"airport\"]}')
print('✅ Basic functionality working!')
"

Building and Validation

• Build the package:

# Clean previous builds
rm -rf build/ dist/ *.egg-info/

# Build package
python -m build

• Validate the package:

twine check dist/*

• Test package installation:

pip install dist/airports_py-*.whl --force-reinstall

Development Scripts

The project includes utility scripts in the scripts/ directory:

Generate Compressed Data File

# Generate airports.gz from airports.json
python scripts/generate_airports_gz.py

# Generate with custom compression level
python scripts/generate_airports_gz.py --compression 6

# Generate with custom source/output files
python scripts/generate_airports_gz.py --source custom_data.json --output custom_data.gz

# Verify existing compressed file
python scripts/generate_airports_gz.py --verify-only

Quick Development Workflow

For ongoing development, use this workflow:

# 1. Make your changes to the code

# 2. Regenerate data file if JSON was updated
python scripts/generate_airports_gz.py

# 3. Run tests
python -m pytest tests/ -v

# 4. Build and validate
python -m build && twine check dist/*

# 5. Test installation
pip install dist/airports_py-*.whl --force-reinstall

Troubleshooting

If you get import errors:

• Ensure you're in the virtual environment: which python should show the venv path
• Verify the package is installed: pip list | grep airports
• Check import works: python -c "import airports.airport_data"

If data file is missing:

• Generate it: python scripts/generate_airports_gz.py
• Verify location: ls -la airports/data/airports.gz
• Check file integrity: python scripts/generate_airports_gz.py --verify-only

If tests fail:

• Ensure data file exists and is valid
• Check that all dependencies are installed: pip install pytest pytest-cov
• Run individual tests: python -m pytest tests/test_airport_data.py::TestAirportData::test_get_airport_by_iata -v

If build fails:

• Ensure setup.py has correct package data configuration
• Check that airports/data/airports.gz exists and is included in package

Deactivating Environment

When you're done developing:

deactivate

Data Management

The airport data is stored in airports/data/ directory:

• airports.json - Source data in JSON format (4.7MB)
• airports.gz - Compressed data used by the library (617KB, 86.9% compression)

Updating Airport Data

• Update the source JSON file:

# Edit airports/data/airports.json with new airport data

• Regenerate the compressed file:

python scripts/generate_airports_gz.py

• Verify the update:

python scripts/generate_airports_gz.py --verify-only
python -c "from airports import airport_data; print(f'Loaded {len(airport_data.airports)} airports')"

• Run tests to ensure compatibility:

python -m pytest tests/ -v

Data Source

This library uses a comprehensive dataset of worldwide airports with regular updates to ensure accuracy and completeness.
