We will try sending a message from the client-side to the server-side. Sending String from One File to the Another File We see the output printed in the server-side terminal. The left window opens up the server.py program, and the terminal on the right opens the client.py program. The screenshot is from two different terminals, one opened in CMD and the other opened in PowerShell in Windows. We need to run server.py and client.py in different terminals, and this is how we will see the connection occur. We take the same port as we had used in our server.py

The tuple here will take host and port in the method. Line 8: There is a binding() method in the server program here, we will use the connect() method. We intend to communicate with sockets to communicate via Python programs on a locally networked machine or even remotely networked machines. It is not in the same machine as we have in this example here. Usually, the client program runs from the server program. The client program also has a similar socket, as we see in the case of the server program. Here is our program for the client: client.py Here we discuss about python socket client: client.py After we are done with our server program, we will be writing out the client program. Lastly, we print a statement that should be displayed when both the programs are running in the terminal. Line 10: This is more like a notification to the server about the connection that has been established. The IP address will be the address of the client where our client is present. Line 9: s.accept() will accept the request from the client, and it returns two objects, one is the socket-client object, and the other is the address. If, for example, the 7 th client comes, then it will be dropped. The numerical represents the number of clients that can interact. Line 8: We have an option to mention the number of the client who can interact with the server. As mentioned before that, we can have multiple clients. Line 7: The bind() method, which binds the host and the port to a socket.ДЄll these steps are needed to start our server.

Any four-digit can be used as mostly the lower digits are occupied. Line 6: We usually have many ports in our system, so we need to make use of a non-used host port. The above are the two parameters that we define for the socket. Line 5: For the hostname, вЂњlocalhostвЂќ or вЂњ127.0.01вЂќ or socket.gethostname() either of these can be used. Then we provide a hostname where the client will connect. TCP is a connection-oriented protocol, essentially involves performing a three-way handshake connection with a server and a client. Next, what is needed is TCP for that, we will need a socket.SOCK_STREAM, which is the socket type. Transmission Control Protocol (TCP) works with the IP and defines how the computer sends data packets to each other.

IPV4 and IPV6 are just different types of IP addresses. IPV4 and IPV6 are different transmission control ways or protocols of transmitting data via the network. AF_INET specifies the protocol that will be used for communication. Line 4: socket.AF_INET corresponds to IPV4 (If one wishes to use IPV6, then socket.AF_INET6 can be used. We are creating an object here, which will call the socket function. This socket module is imported into the python program, and it will be used as a socket function later in the program. Line 3: Socket is a pre-installed library, and an object will be created for that. Have a look at the program below: server.py TCP also provides in-order data delivery, i.e., the order in which the sender sends it in a similar order the application reads it. TCP is reliable as the packets which are dropped in the network are detected and transmitted by the sender. Transmission Control Protocol(TCP) is the default protocol that is chosen.
