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)))

dictsearch

dictSearch(3)							    util/dict.h 						     dictSearch(3)

NAME

       dictSearch  - search for value in dictionary.

SYNOPSIS

       #include <util/dict.h>

       void *dictSearch(dictCtx dict, const char *id, void **plock);

ARGUMENTS

       dict - dictionary to search in.
       id - identifier of item to find.
       plock - place for value lock (or NULL).

DESCRIPTION

       Searches for <id> in <dict>, and returns value if found, or NULL if not.  If <plock> is non-NULL, then the lock returned in <plock> will be
       associated with the returned value.  Until this lock is passed to dictReleaseLock(), the value will not be passed  to  the  dictCleanupFunc
       callback (see dictCleanup()).

       MT-Level: Safe if <dict> thread-safe.

RETURN VALUE

       plock - set to value lock.
