Overview of this book

Python is a multi-domain, interpreted programming language. It is a widely used general-purpose, high-level programming language. It is often used as a scripting language because of its forgiving syntax and compatibility with a wide variety of different eco-systems. Python GUI Programming Cookbook follows a task-based approach to help you create beautiful and very effective GUIs with the least amount of code necessary. This book will guide you through the very basics of creating a fully functional GUI in Python with only a few lines of code. Each and every recipe adds more widgets to the GUIs we are creating. While the cookbook recipes all stand on their own, there is a common theme running through all of them. As our GUIs keep expanding, using more and more widgets, we start to talk to networks, databases, and graphical libraries that greatly enhance our GUI’s functionality. This book is what you need to expand your knowledge on the subject of GUIs, and make sure you’re not missing out in the long run.

Using TCP/IP to communicate via networks


This recipe shows you how to use sockets to communicate via TCP/IP. In order to achieve this, we need both an IP address and a port number.

In order to keep things simple and independent of the ever changing internet IP addresses, we will create our own local TCP/IP server and, as a client, learn how to connect to it and read data from a TCP/IP connection.

We will integrate this networking capability into our GUI by using the queues we created in the previous recipes.

Note

TCP/IP stands for Transmission Control Protocol/Internet Protocol, which is a set of networking protocols that allows two or more computers to communicate.

Getting ready

We will create a new Python module which will be the TCP server.

How to do it…

One way to implement a TCP server in Python is to inherit from the socketserver module. We subclass BaseRequestHandler and then override the inherited handle method. In very few lines of Python code, we can implement a TCP server:

    from socketserver...
