See the "struct" module (http://docs.python.org/lib/module-struct.html) for a couple of really useful functions. For example, you could use: >>> GEN_STREAMTYPE_NULL = 0x51 >>> def send4bytes(num): ... mysocket.send(struct.pack("L", num)) ... >>> send4bytes(GEN_STREAMTYPE_NULL) As for bit manipulation--it's built in, just like in C. >>> hex(0x1234 & 0xFF) '0x34' >>> hex(0x34 << 8) '0x3400' Hope this helps. -- David -- http://mail.python.org/mailman/listinfo/python-list
