Sure there is:

if sys.executable.endswith("_d.exe"):
  print "Debug version"

If relying on the executable name is too unsafe, you can also look
at imp.get_suffixes(), which includes "_d.pyd" in a debug build on
Windows.

If you want it cross-platform, you can check whether sys.getobjects
is available. That, of course, is also unsafe because there isn't
a single "debug build" on Unix, but instead, several debugging
features can be enabled and disabled separately, so you would have
to specify first what precisely a debug build is.
