I'm one of the few (thousand) hard core Eiffel programmers on this
world
and i can tell you that this would not add to much to python. To get
the
benefits of it you need to use it together with a runtime that is
designed
from ground with DBC and a language that is fast enough to be able to
check the contracts, if you don't have the latter all you get is a
better
specification language (which you can write as comments in python).

Learn the Eiffel design way and then add assert statements whereever
you
need them. Works well when i do C/C++ programming and maybe even for
script languages - but i never used it for scripts as i don't see a
real
value here.
