Python - creating byte arrays help
Hi
I have my TCP connection, server listen code fleshed out.
On the client, though,
I'd like to create a byte array of a certain length, with a tag number.
How do I do this?
basically Java,
byte[] data = new byte[500] // is that the correct size for a TCP network game HELO message? smaller? can be 3 . . .
data[0] = HELO_MSG byte
data[1] = client number byte #1
data[2] = client number byte #2
That's all? no need for more than 256 clients..so, one byte.
The client port, address, etc is gathered from this message.
I can send and listen, but I don't know how to create a blank byte[] of x size and fill it with certain numbers?
byte[] data = new byte[3]
What about in game messages, that can be hundreds of bytes?

Thanks
bytearray is the answer
am doing
data=bytearray(5)
data[0]= MSG_HELO
and it sends this over TCP the same.

Is that right? It didn't explode.
How do I make a bigger byte array for in-game messages? Or are they not big. I'm thinking big because of movements of large numbers of units. Must I keep groupings of units registered in the server?
How can I set the size of each type of message byte array?
Incidentally, when I hardcoded the byte array, my other socket explosions stopped.
