Note: you can also use encode() and decode() methods on the string 
containing your data, specifying 'zip' as encoding.

Example:

 >>> s="Hello"*100
 >>> s1 = s.encode('zip')
 >>> len(s1)
18
 >>> s1
'x\x9c\xf3H\xcd\xc9\xc9\xf7\x18%F\x12\x01\x00\t\xb9\xc3Q'
 >>> s2 = s1.decode('zip')
 >>> len(s2)
500
 >>> s2
'HelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHell
oHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHell
oHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHell
oHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHell
oHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHell
oHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHelloHell
oHelloHelloHelloHello'
 >>>


IMHO this is mode understandable than zlib.decompress( data, 
-zlib.MAX_WBITS ).

A+

Laurent.

PS. There may be other compression encodings... look at 
encodings.aliases.aliases, where I can see 'zip' and 'zlib' (same), but 
also 'bz2'. - you can also found encoders for hexadecimal, quoted 
printable, and other formats.
