These are the official Python bindings to https://github.com/openvenues/libpostal, a fast statistical parser/normalizer for street addresses anywhere in the world.
from postal.expand import expand_address
expand_address('Quatre vingt douze Ave des Champs-Élysées')
from postal.parser import parse_address
parse_address('The Book Club 100-106 Leonard St, Shoreditch, London, Greater London, EC2A 4RH, United Kingdom')Before using the Python bindings, you must install the libpostal C library. Make sure you have the following prerequisites:
On Ubuntu/Debian
sudo apt-get install curl autoconf automake libtool python-dev pkg-config
On CentOS/RHEL
sudo yum install curl autoconf automake libtool python-devel pkgconfig
On Mac OSX
brew install curl autoconf automake libtool pkg-config
Installing libpostal
git clone https://github.com/openvenues/libpostal
cd libpostal
./bootstrap.sh
./configure --datadir=[...some dir with a few GB of space...]
make
sudo make install
# On Linux it's probably a good idea to run
sudo ldconfig
To install the Python library, just run:
pip install postal
pypostal supports Python 2.7+ and Python 3.4+. These bindings are written using the Python C API and thus support CPython only. Since libpostal is a standalone C library, support for PyPy is still possible with a CFFI wrapper, but is not a goal for this repo.
Make sure you have nose installed, then run:
python setup.py build_ext --inplace
nosetests postal/tests
The build_ext --inplace business is needed so the C extensions build in the source checkout directory and are accessible/importalbe by the Python modules.
