Python equivalent of shell's '$?'

If I call an external program from a python script, how do I check that
programs exit status? In sh I would simply check the $? variable, but I
can't seem to find any equivalent in python. Or does python suffer from
the same unreliabilty as perl in this regard (I've learnt that catching
errors from sub shells is highly unreliable, and ended up having not
checking for errors, as I would sometimes get spurious results back).
Any info much appreciated.
Cheers
Dave
