deep.py gives you something like regular expressions for data structures and objects. This ranges from checking that 2 structures are identical to checking that some parts of a structure matches certain criteria while ignoring other parts.

This module is a rewrite and refactoring of the guts of Test::Deep (http://search.cpan.org/dist/Test-Deep/ a Perl testing module). The interface has been improved but there are some features missing still.

The version control is in a bit of a state of flux at the moment. Up to 0.4 is in SVN here, which was mirrored from a mercurial repository. I have now switched to git and used that for 0.5 but the SVN repo here has not been updated. At the moment, only the tar-ball is available.
