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 urlopen to read data from websites


This recipe shows how we can easily read entire web pages by using Python's built-in modules. We will display the web page data first in its raw format and then decode it, and then we will display it in our GUI.

Getting ready

We will read the data from a webpage and then display it in the ScrolledText widget of our GUI.

How to do it…

First, we create a new Python module and name it URL.py. We then import the required functionality to read webpages using Python. We can do this in very few lines of code.

We wrap our code in a try...except block similar to Java and C#. This is a modern approach to coding, which Python supports. Whenever we have code that might not complete, we can experiment with this code and, if it works, all is fine. If the block of code in the try...except block does not work, the Python interpreter will throw one of several possible exceptions, which we can then catch. Once we have caught the exception, we can decide what to do next...
