Code snippets

This implementation IS FULLY 30W-compliant.

Various code snippets can be found at Implementations/Libraries/Python.

Python package xkcd.geohash

This implementation IS NOT 30W-compliant.

There is Python package xkcd.geohash which is independent of the interactive coordinate calculator (but uses Google Finance as well).

Python 3 standard library

In Python 3.1 and above, an implementation of the geohashing algorithm is included in the antigravity module. Unfortunately importing the module will open a web browser.

>>>import antigravity
(opens the xkcd comic)
>>>antigravity.geohash(34,-118,b'2012-04-09-13057.57')
34.386614 -118.231675
