Today, looking for half a day on the Internet, found that many of the programs on this topic can only receive data, so randomly find a program to study a little, and then make some changes
The code is as follows:
from socket import *
import threading
tcp_socket = socket(AF_INET, SOCK_STREAM)
tcp_socket.connect(('192.168.1.102', 8080))
true = True
def rece_msg(tcp_socket):
global true
while true:
recv_msg = tcp_socket.recv(1024).decode("utf8")
if recv_msg == "exit":
true = False
print('Received message as: %s' % recv_msg)
def send_msg(tcp_socket):
global true
while true:
send_msg = input('Please enter the content to be sent')
tcp_socket.send(send_msg.encode('utf-8'))
if send_msg == "exit":
true = False
def main():
while True:
print('*'*50)
print('1 Send message \n2 Receive message')
option = int(input('Please select the content of the operation'))
print('*'*50)
if option == 1:
(target=send_msg, args=(tcp_socket,)).start()
elif option == 2:
(target=rece_msg, args=(tcp_socket,)).start()
else:
print('Input error')
break
if __name__ == '__main__':
main()
This code can only be implemented to either always send or always receive
Runs as shown

To solve the problem of sending and receiving only unilaterally, the code is modified as follows
from socket import *
import threading
tcp_socket = socket(AF_INET, SOCK_STREAM)
tcp_socket.connect(('192.168.1.102', 8080))
true = True
def rece_msg(tcp_socket):
global true
while true:
recv_msg = tcp_socket.recv(1024).decode("utf8")
if recv_msg == "exit":
true = False
print('The message received is: %s\n' % recv_msg)
def send_msg(tcp_socket):
global true
while true:
send_msg = input('Please enter the content to be sent\n')
tcp_socket.send(send_msg.encode('utf-8'))
if send_msg == "exit":
true = False
(target=send_msg, args=(tcp_socket,)).start()
(target=rece_msg, args=(tcp_socket,)).start()
running result
