Your approach is nearly right. First of all, you have to tell
struct.unpack it should unpack from network order ("!"):
>>> struct.unpack('!H', inp)[0]
1024
Then you want to repack it in host byte order. Use "=" for that.
>>> out = struct.pack('=H', struct.unpack('!H', inp)[0])
>>> out
'\x00\x04'
For more information, look for "Size and alignment" in
http://docs.python.org/library/struct.html.
