Python - how do I - array of IPAddresses?

Hi
Thanks for getting me this far in my server code.

My clients are all joining, but I need the best way of storing client information for later use.
I basically need an array of structs for the clients, like
struct client {
ipaddress address;
int PORT;
}
Their index in the array of client information would correspond with their client number.
I'm considering having an array of addresses and an array of PORTS, - should that be enough info for the clients?
maybe, also a boolean if they are still connected?

What is the code for declaring an array of ipaddresses?
or, how do I declare an array of tuples? structs?

Thanks

I can make an array of bytes

bytearray(100)
will give you 100 zero bytes.

How does it work for complex data?

If you just want to keep track of this information and if you don't have to store the data in a memory optimized way:


Why don't you just make a list of objects.
or a dict of objects (acting as a sparse array)

Is there any erason you want to declare that array.
WOuldn't it be enough to add new client info whenever you have new data.

class ClientInfo():
    def __init__(self, ip=None, port=None):
        self.ip = ip
        self.port=port

clients = []




to create a new client you would just write
clients.append(ClientInfo('127.0.0.1', 8080)

# next line of you want to keep the index of the client
client_idx = len(clients)-1

please give me more context if I misunderstood your question

I would just like to store the client info once the clients in the game arrive.

If the server expects n clients, the clients may, will arrive out of order.

Last time I did an RTS, in Java, I declared an array of clientInfo objects, because I knew how many to expect.
- And I assign a client a clientNumber corresponding to the order in which they joined?
So the ClientInfo code above goes in the server .py  - even tho it is a class? and the server class code after it?

Wouldn't I also need a ClientNumber parameter? clientnumber?
ClientNumber = clientnumber
