You might be able to tackle this easily enough with REs if your
structures don't nest arbitrarily.  It's hard to tell if this deserves
a formal grammar based on the example.  If it does, you could try PLY
<http://www.dabeaz.com/ply/> (which I've had a pleasant experience
with in the past) or any of the other parsers listed on the PLY site's
"Other Python Parsing Tools".
