Richard Tew posted a new release of DS Python on his site, heres the info:
This is a port of Python 2.4.3 to the Nintendo DS, specifically, a port of the Stackless version of Python. The normal Python functionality is as far as I know, bug free. However, the Stackless scheduler is broken and locks up when started. But this is nothing to worry about, ignoring that this is a modified version of Python and just using it like the normal one will work fine.
There are two versions provided. The FAT version which includes chishm's FAT filesystem support, which allows Python source code to be read from homebrew devices. I, for instance, have a compact flash based Supercard and source code is read from this when imported.
