If you are new to socket programming, then you would certainly benefit from reading from the below Python tutorials.<\/p>\n\n\n\n
Create TCP Server and Client in Python<\/h2>\n\n\n\n
To understand the topic in detail, let’s first have a quick look at the socket classes present in the Python SocketServer<\/strong><\/em> module. It is a framework that wraps the Python socket functionality. For your note, this component has a new name There are two types of built-in classes in the TCPServer class –<\/strong> It follows the (Internet) TCP protocol that allows continuous streams of data between the server and client.<\/p>\n\n\n\n UDPServer class –<\/strong> It makes use of datagrams that contains discrete packets of information. They may go out of order or get dropped in transit.<\/p>\n\n\n\n UnixStreamServer And UnixDatagramServer classes –<\/strong> These classes are similar to the TCP and UDP classes but use Unix domain sockets. Both of them don’t support non-Unix platforms.<\/p>\n\n\n\n The above four classes process the calls synchronously; they accept\u00a0and treat the requests in a strict sequence. This behavior doesn’t scale if each call takes a long time to complete. It returns a lot of data that the client is not able to process instantly.<\/p>\n\n\n\n The solution is to allow multiple threads to take care of each request. Below is the list of classes to manage each connection on separate threads.<\/p>\n\n\n\n The Now let’s see the example of the Python TCP Server.<\/p>\n\n\n\n In the next example code, you’ll see the Python TCP client module code to communicate with the TCP server.<\/p>\n\n\n\n You can run both the server and client in separate Python instances. We recommend that you use Python version 3 for executing the above modules.<\/p>\n\n\n\n Next, you would first run the server module followed by the client. See below the output of both the client and the server.<\/p>\n\n\n\n We always share what we think is useful for our readers like this blog post and other ones in the series of Python socket programming. We hope this Python tutorial and the TCP server example would have served your purpose to visit our blog.<\/p>\n\n\n\n So, do give us your support and share this post using the sharing icons given below.<\/p>\n\n\n\n Lastly, we believe that Python is powerful and it works to the expectations.<\/p>\n\n\n\n Best,<\/strong><\/p>\n\n\n\n TechBeamers<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":" Python is one of the most popular object-oriented scripting languages with a programmer-friendly syntax and a vast developer community.
