in what form?

    sock.send(chr(100)) # single byte
    sock.send(str(100)+"\n") # ascii characters plus newline
    sock.send(str(100)+":") # netstring prefix
    sock.send("%08d" % 100) # eight ascii characters, null-padded
    sock.send(str(100).encode("utf-16")) # same, in utf-16 with bom
    sock.send(struct.pack("!i", 100)) # 32-bit integer in network byte order

etc.  (see the struct module documentation for more alternatives)
