Tested and working.

Code:
#!/usr/bin/env python

import sys

input = open(sys.argv[1], 'r')

dict = {}

for line in input:

    line = line.rstrip()

    if line.count("|"):
        line = line.split("|")
        if dict.has_key(line[0]):
            dict[line[0]].extend(line[1:3])
        else:
            dict[line[0]] = line[1:3]
            
input.close()

for key, value in dict.items():

    print("%s|%s" % (key, "|".join(value)))

NAME

       british-english - a list of English words

DESCRIPTION

       /usr/share/dict/british-english is an ASCII file which contains an alphabetic list of words, one per line.

FILES

       There  may  be  any  number  of	word lists in /usr/share/dict/.  /etc/dictionaries-common/words is a symbolic link to the currently-chosen
       /usr/share/dict/<language> file.  /usr/share/dict/words is a symbolic link to /etc/dictionaries-common/words, and  is  the  name  by  which
       other  software should refer to the system word list.  See select-default-wordlist(8) for more information, and/or to change the currently-
       chosen word list.

       The directory /usr/share/dict can contain word lists for many languages, with name of the language in English, e.g., /usr/share/dict/french
       and  /usr/share/dict/danish  contain respectively lists of French and Danish words if they exist.  Such lists should be coded using the ISO
       8859-1 character set encoding.

SEE ALSO

       ispell(1), select-default-wordlist(8), and the Filesystem Hierarchy Standard.

HISTORY

       The words lists are not specific, and may be generated from any number of sources.

       The system word list used to be /usr/dict/words.  For compatibility, software should check that location if /usr/share/dict/words does  not
       exist.

AUTHOR

       Word  lists  are  collected and maintained by various authors.  The Debian English word lists are built from the SCOWL (Spell- Checker Ori-
       ented Word Lists) package, whose upstream editor is Kevin Atkinson <kevina@users.sourceforge.net>.
