A strange value is added during socket communication.

The server is Java and the client is Python.

Java sends a string to writeUTF.

Server code.

    public void sendPacket(String packet) {
        try {
            out.writeUTF(packet);
            out.flush();
        } } catch (IOException e) {
        }
    }

    sendPacket(WebAction.Index.getServerMessage());

Client code.

        soc.connect(("127.0.0.1", 7824))
        writeString(soc, "ServerMsg&")
        msg = soc.recv(1024)

Below is a picture of the problem.

'In addition, there are times when numbers are added and sometimes letters are added. I posted a few questions, but I'm posting them again because you gave me a lot of good answers. Thank you for your time.

I don't know why, but if there's always a strange character in front of the string,

HOST='127.0.0.1'
PORT=5007
s=socket(AF_INET,SOCK_STREAM)
#s.bind(HOST, PORT)
s.connect(('127.0.0.1', 8821))

data=s.recv(1024)
data = data[2:]
s.close()
print('Received : %s' % data)

data = data[2:] I think we can use this method of cutting the first letter.
