I use constraints programming at work, Check out "System Verilog" or
OZ/Mozart.

It would be great if this style of programming could be added to
Python.

It is a declarative programming style
(http://en.wikipedia.org/wiki/Declarative_programming), in which you
can state what discrete values constrained values can take , say in a
list. Give a set of functions that must be true for the variables then
sit back and generate one or many sets of variable values that fit the
constraints.

The OZ homepage has an example for solving the eight queens problem:

My use would be for testing. In the electronic design automation
fields, there are several proprietary languages with this feature, here
is an example written in Cadence's Specman 'e' language:
