Mmm... although I have discovered a debian package called pydf whose
source made interesting reading.

That sounds fascinating... and something to play with.

In the end I just did:

def fsUsage(dir):
  """Returns the % usage of a given filesystem"""
  stat = os.statvfs(dir)
  from statvfs import F_BLOCKS, F_BFREE
  total = stat[F_BLOCKS]
  avail = stat[F_BFREE]
  used = total-avail
  percent = used/total*100
  return percent
