zipcodetw 0.3

Find Taiwan ZIP code by address fuzzily.

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. Lightweight. It depends on nothing.

Usage

Find ZIP code gradually:

>>> import zipcodetw
>>> zipcodetw.find('臺北市')
'1'
>>> zipcodetw.find('臺北市信義區')
'110'
>>> zipcodetw.find('臺北市信義區市府路')
'110'
>>> zipcodetw.find('臺北市信義區市府路1號')
'11008'

After v0.3, you can find ZIP code fuzzier:

>>> zipcodetw.find('松山區')
'105'
>>> zipcodetw.find('秀山街')
''
>>> zipcodetw.find('台北市秀山街')
'10042'
