Remember to:

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

:warning: Do not pip install anything that isn't related to your question, especially if asked to over DMs.

Closes after a period of inactivity, or when you send !close.

Can you elaborate?

Show the code you have so far and the error message

[celest wedge]

kill -9 $(ps -A | grep python | awk '{print $1}')

import socket

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

server_address = ('localhost', 6969)
server_socket.bind(server_address)
server_socket.listen(2)

print("Server is listening...")

client_socket, client_address = server_socket.accept()
print(f"Connection established with {client_address}")

x = []
while True:

data = client_socket.recv(1024).decode('utf-8')
if data:
    print(f"Received: {data}")

    x.append(data)

print(x)

client_socket.close()
server_socket.close()

If it's disconnected from the client's side, then you cannot reconnect, unless client is also a kind of server (waits for connections). Because normally client only has a temporary port for the current communication

[celest wedge]

what if the client get disconnected by some tech. issue how do you reconnect then without restarting the server

[solemn geyser]

There's got to be code on the client

Do you really need to be using plain sockets?

[celest wedge]

i am just learning about them

[solemn geyser]

Perhaps you could use Https?

You need to do framing and explicit eof

without restarting the server

Just don't kill the server when client disconnects. Does a website closes when you no longer use it? No, it waits for more connections.

You can do it by having a server create a thread for each client, while main thread still waits for connections

Or use select, but it's more tricky

This simple tutorial has an example of loop and starting thread per client, very simple https://docs.python.org/3/howto/sockets.html

while True:
    # accept connections from outside
    (clientsocket, address) = serversocket.accept()
    # now do something with the clientsocket
    # in this case, we'll pretend this is a threaded server
    ct = client_thread(clientsocket)
    ct.run()

You'll need to use a cookie to associate clients with reconnections

And you might need message numbers and a buffer so you can resend what's missed and so you know what's missed
