Hey @hollow path!

It looks like you pasted Python code without syntax highlighting.

Please use syntax highlighting to improve the legibility of your code and make it easier for us to help you.

To do this, use the following method:
```py
print('Hello, world!')
```

This will result in the following:

print('Hello, world!')```
You can **edit your original message** to correct your code block.

@hollow path the code keeps on getting deleted because we filter out the slur in it

oh my bad

xd

i forgot to remvoe it

gg

once a client reconnects, i cant take input and send. anyone knows what i am doing wrong?

import socket
import threading
import time

def receiveData(conn):
    while True:
        try:
            data = conn.recv(1024)
            if not data:
                break
            decodedData = data.decode()
            print(f"Received data: {decodedData}")
        except ConnectionResetError:
            print("connected reset by client.")
            print("waiting for new client")
            break
        except ConnectionAbortedError:
            print("connection aborted.")
            break
        except Exception as e:
            print(f"Error receiving data: {str(e)}")
            break

def sendData(conn):
    while True:
        try:
            if conn:
                userInput = input("what do you want to send? ").strip()
                conn.sendall(userInput.encode())
                time.sleep(3)
        except Exception as e:
            print(f"Error sending data: {str(e)}")
            print("will try to ask for new input again")
            continue
        except KeyboardInterrupt:
            print("dont press ctrl.")
            continue

def ClientHandle(server):
    while True:
        conn, addr = server.accept()
        print(f"New client connected: {addr}")
        t_receive = threading.Thread(target=receiveData, args=(conn,))
        t_send = threading.Thread(target=sendData, args=(conn,))
        t_receive.start()
        t_send.start()

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
host = "192.168.0.148"
port = 6666

server.bind((host, port))
server.listen()

t_new_client = threading.Thread(target=ClientHandle, args=(server,))
t_new_client.start()
t_new_client.join()

it was working earlier today. idk what i did to make it not work

[gilded girder]

I think i may have found the issue
python doesn't like it when multiple threads try to call input() at the same time, so once you've got two things connected (and two threads running sendData), if they ever both try to input() at the same time, the whole thing crashes, and in a way that means it cant print out any sort of traceback error message

[hollow path]

i think i will look at again tmr

kinda lost rn

could i like make a seperate function taking input then pass a paramter in senddata function

[gilded girder]

yeah, possibly, the main point is that functions need to be careful about when they try and call input()
this is the sort of problem where you'll have to start looking into the world of things like threading synchronisation - threading.Lock might be of interest
