14.19 The soundex Module

(Optional, Only 1.5.2) The soundex module implements a simple hash algorithm, which converts words to 6-character strings based on their English pronunciation.

As of Version 2.0, this module is no longer included.

get_soundex(word) returns the soundex string for the given word. Words that sound similar should give the same soundex string. sound_similar(word1, word2) returns true if the two words have the same soundex. Example 14-24 uses both functions.

Example 14-24. Using the soundex Module

File: soundex-example-1.py

import soundex

a = "fredrik"
b = "friedrich"

print soundex.get_soundex(a), soundex.get_soundex(b)

print soundex.sound_similar(a, b)
