Find Taiwan ZIP code by address fuzzily.
This package lets you find ZIP code by address in Taiwan.
The main features:
- Fast. It builds ZIP code index by tokenization.
- Gradual. It returns partial ZIP code rather than noting when address is not detailed enoguh.
- Stand-alone. It depends on nothing.
Find ZIP code gradually:
>>> import zipcodetw >>> zipcodetw.find('臺北市') u'1' >>> zipcodetw.find('臺北市信義區') u'110' >>> zipcodetw.find('臺北市信義區市府路') u'110' >>> zipcodetw.find('臺北市信義區市府路1號') u'11008'
After v0.3, you even can find ZIP code like:
>>> zipcodetw.find('松山區') u'105' >>> zipcodetw.find('秀山街') u'' >>> zipcodetw.find('台北市秀山街') u'10042'
It is available on PyPI:
$ sudo pip install zipcodetw
Just install it and have fun. :)
Build Index Manually
If you install it by pip or python setup.py install, a ZIP code index will be built automatically. But if you want to use it from source code, you have to build an index manually:
$ python -m zipcodetw.builder
The ZIP code directory is provided by Chunghwa Post, and is available from: http://www.post.gov.tw/post/internet/Download/all_list.jsp?ID=2201#dl_txt_s_A0206
