Try this:

     import zlib

     compressor = zlib.compressobj(6) # level
     cmpr = compressor.compress("a")
     print "compressed: %d %r" % (len(cmpr), cmpr)
     cmpr_rest = compressor.flush()
     print "compressed: %d %r" % (len(cmpr_rest), cmpr_rest)
     decompressor = zlib.decompressobj() # wbits
     a = decompressor.decompress(cmpr)
     b = decompressor.decompress(cmpr_rest)
     c = decompressor.flush()
     print "decompressed: %d+%d+%d: %r %r %r" % (
             len(a), len(b), len(c), a, b, c)
