I had this same question a while back and came to find out that the IDL
save file format does not have a public description and that RSI
reserves the right to change the format at any time they want. In
short, they don't want people to know the format or to start messing
around with their save files.

With the way that Python data structures work, it doesn't seem like
there would be any good way to directly translate an array of structures
in IDL to something in Python. If I may ask, why are you attempting to
use IDL and Python together in this way? I ask only because there may
be another way to go about solving your problem so there'll be less
burden on the Python side, which seems to be the bottleneck.

I have written programs where IDL has communicated with programs in
other languages (e.g. Python, Java), but each time I've written
something extremely specific rather than trying to find the general
solution. That may be what you need to do -- code the specific solution
such that you can make the best use of Python for this particular project.
