The main difference between server and client program is, in server program, it needs to bind host address and port address together.

Socket For Python In Software That Waits

So, what is a server Well, a server is a software that waits for client requests and serves or processes them accordingly.

A client program request for some resources to the server and server responds to that request.

Socket is the endpoint of a bidirectional communications channel between server and client.

Sockets may communicate within a process, between processes on the same machine, or between processes on different machines.

For any communication with a remote program, we have to connect through a socket port.

The main objective of this socket programming tutorial is to get introduce you how socket server and client communicate with each other.

Socket For Python In How To Write Python

You will also learn how to write python socket server program.

Python Socket Example We have said earlier that a socket client requests for some resources to the socket server and the server responds to that request.

So we will design both server and client model so that each can communicate with them.

Python socket server program executes at first and wait for any request Python socket client program will initiate the conversation at first.

Then server program will response accordingly to client requests.

Server program will also terminate when client program terminates, this is optional and we can keep server program running indefinitely or terminate with some specific command in client request.

Python Socket Server We will save python socket server program as socketserver.py.

To use python socket connection, we need to import socket module.

Then, sequentially we need to perform some task to establish connection between server and client.

We can obtain host address by using socket.gethostname() function.

It is recommended to user port address above 1024 because port number lesser than 1024 are reserved for standard internet protocol.

See the below python socket server example code, the comments will help you to understand the code.

If you want server to not quit when client connection is closed, just remove the if condition and break statement.

Python Socket Client We will save python socket client program as socketclient.py.

This program is similar to the server program, except binding.
