Do it the hard way:

  def ShowSize(raw):
    if raw < 3000:
      return "%d" % raw
    elif raw < 2000000:
      return "%dk" % (raw / 1000)
    elif raw < 2000000000L:
      return "%dM" % (raw / 1000000)
    else:
      return "%dG" % (raw / 1000000000L)

Actually, I usually use a few more cases so that I always get two
significant digits:  1.2k, 23k, 840k, 2.4M, etc.
