numpy + scipy offer a lot, but it's more on the maths side of things than the rather streamlined, relatively elegant and specific items you are used from XSIMath; it will also miss some things and interoperability between types you are used to which aren't strictly standard in the actual math sciences domain (XSIMath falls clearly into applied/specific).
>From there you can also poke pypi (the official package repository) at https://wiki.python.org/moin/CheeseShopTutorial You can find a bunch of rather good libraries for things like quaternions, anisotropic arrays and their applications, rotation management, and some games related stuff that for obvious reasons is very affine with what you are used to. There is nothing that is going to be an obvious replacement to the full extent of functionalities you are used to all in one place, you will have to pick and choose and collate through your own wrapper to have that kind of experience again. iMath is in use all over the place in VFX because it's there, but to be honest I find it reads and writes rather clumsily, bindings support is always a roll of the dice, and it's not exactly covering all of XSIMath in terms of flow, though it offers a lot more as it covers other subjects not included in XSIMath due to its use in exr and other alembic, things like signal related problems, spherical problems, harmonics etc. There used to be a set of 100% complete bindings here: http://code.google.com/p/pimath/ Which I used with success the last time I trialled it. But those were last up to date when DrD here in Sydney was still standing, it's probably rather outdated or even non-functionally obsolete these days.
