zipcodetw 0.5.1

Find Taiwan ZIP code by address fuzzily.

Latest Version: 0.6

The ZIP Code Finder for Taiwan

This package lets you find ZIP code by address in Taiwan.

The main features:

  1. Fast. It builds ZIP code index by tokenization.
  2. Gradual. It returns partial ZIP code rather than noting when address is not detailed enoguh.
  3. Stand-alone. It depends on nothing.


Find ZIP code gradually:

>>> import zipcodetw
>>> zipcodetw.find('臺北市')
>>> zipcodetw.find('臺北市信義區')
>>> zipcodetw.find('臺北市信義區市府路')
>>> zipcodetw.find('臺北市信義區市府路1號')

After v0.3, you even can find ZIP code like:

>>> zipcodetw.find('松山區')
>>> zipcodetw.find('秀山街')
>>> zipcodetw.find('台北市秀山街')


It is available on PyPI:

$ sudo pip install zipcodetw

Just install it and have fun. :)

$ python -m zipcodetw.builder
