Gabriel and other perplexed readers:  I *think* the original
questioner has in mind C++'s multimaps <URL:
http://www.cplusplus.com/reference/stl/multimap/ >, imple-
mented, among other places, in the C++ Standard Template
Library.  What puzzles *me* is his his insistence, if I 
understand him correctly, that Python's lists don't aptly
model multimap containers; from everything I know, a defin-
ing characteristic of multimap containers that they are
strictly ordered.  Perhaps someone more current in C++ can
explain.
