Those common functions can go in your modules directory. Use local_import to have access to them in your code as explained in http://web2py.com/book/default/chapter/04#Third-Party-Modules > Here is the Soundex code: > > def soundex(name, len=4): > """ soundex module conforming to Knuth's algorithm > implementation 2000-12-24 by Gregory Jorgensen public domain > """ > > # digits holds the soundex values for the alphabet > digits = '01230120022455012623010202' > sndx = '' > fc = '' > > # translate alpha chars in name to soundex digits > for c in name.upper(): > if c.isalpha(): > if not fc: fc = c # remember first letter > d = digits[ord(c)-ord('A')] > # duplicate consecutive soundex digits are skipped > if not sndx or (d != sndx[-1]): > sndx += d > > # replace first digit with first alpha character > sndx = fc + sndx[1:] > > # remove all 0s from the soundex code > sndx = sndx.replace('0','') > > # return soundex code padded to len characters > return (sndx + (len * '0'))[:len] > > 2.
