Overview of this book

Learning Python has a dynamic and varied nature. It reads easily and lays a good foundation for those who are interested in digging deeper. It has a practical and example-oriented approach through which both the introductory and the advanced topics are explained. Starting with the fundamentals of programming and Python, it ends by exploring very different topics, like GUIs, web apps and data science. The book takes you all the way to creating a fully fledged application. The book begins by exploring the essentials of programming, data structures and teaches you how to manipulate them. It then moves on to controlling the flow of a program and writing reusable and error proof code. You will then explore different programming paradigms that will allow you to find the best approach to any situation, and also learn how to perform performance optimization as well as effective debugging. Throughout, the book steers you through the various types of applications, and it concludes with a complete mini website built upon all the concepts that you learned.

Second approach – a GUI application


There are several libraries to write GUI applications in Python. The most famous ones are tkinter, wxPython, PyGTK, and PyQt. They all offer a wide range of tools and widgets that you can use to compose a GUI application.

The one I'm going to use for the rest of this chapter is tkinter. tkinter stands for Tk interface and it is the standard Python interface to the Tk GUI toolkit. Both Tk and tkinter are available on most Unix platforms, Mac OS X, as well as on Windows systems.

Let's make sure that tkinter is installed properly on your system by running this command:

$ python -m tkinter

It should open a dialog window demonstrating a simple Tk interface. If you can see that, then we're good to go. However, if it doesn't work, please search for tkinter in the Python official documentation. You will find several links to resources that will help you get up and running with it.

We're going to make a very simple GUI application that basically mimics the behavior...
