I want to get a code about tcp with python

Here is an example code for creating a TCP client in Python:

import socket

# create a socket object
client_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# get the server IP address and port number
server_address = ('localhost', 8888)

# connect to the server
client_socket.connect(server_address)

# send a message to the server
message = 'Hello, server!'
client_socket.sendall(message.encode())

# receive a response from the server
data = client_socket.recv(1024)
print('Received:', data.decode())

# close the connection
client_socket.close()

And here is an example code for creating a TCP server in Python:

import socket

# create a socket object
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# bind the socket to a server address and port number
server_address = ('localhost', 8888)
server_socket.bind(server_address)

# listen for incoming connections
server_socket.listen(1)

while True:
    # accept a client connection
    client_socket, client_address = server_socket.accept()
    print('Connection from:', client_address)

    # receive a message from the client
    data = client_socket.recv(1024)
    print('Received:', data.decode())

    # send a response to the client
    message = 'Hello, client!'
    client_socket.sendall(message.encode())

    # close the client connection
    client_socket.close()

Note that in both examples, we are using the `socket` module to create a TCP socket object, and the `sendall()` and `recv()` methods to send and receive data over the connection.
