How to create sockets in python

 In Python, you can use the socket module to create sockets (communication channels) for sending and receiving data over a network.

Here is an example of how to create a socket in Python:

import socket

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

# get local machine name
host = socket.gethostname()

# reserve a port for your service
port = 9999

# bind the socket to a public host, and a port
s.bind((host, port))

# become a server socket
s.listen(5)

# establish a connection
conn, addr = s.accept()

print('Connected by', addr)

# close the connection
conn.close()

In this example, we use the socket() function to create a socket object. The first argument specifies the address family (AF_INET for IPv4) and the second argument specifies the type of socket (SOCK_STREAM for a TCP socket).

Then, we use the bind() function to bind the socket to a host and port. The listen() function tells the socket to start listening for incoming connections.

Finally, the accept() function waits for an incoming connection and returns a tuple containing the connection object and the address of the client.

Once a connection is established, you can send and receive data using the connection object's send() and recv() methods.

# send data
conn.send(b'Hello, World!')

# receive data
data = conn.
