Overview of this book

Tkinter is the built-in GUI package that comes with standard Python distributions. It is a cross-platform package, which means you build once and deploy everywhere. It is simple to use and intuitive in nature, making it suitable for programmers and non-programmers alike. This book will help you master the art of GUI programming. It delivers the bigger picture of GUI programming by building real-world, productive, and fun applications such as a text editor, drum machine, game of chess, media player, drawing application, chat application, screen saver, port scanner, and many more. In every project, you will build on the skills acquired in the previous project and gain more expertise. You will learn to write multithreaded programs, network programs, database driven programs and more. You will also get to know the modern best practices involved in writing GUI apps. With its rich source of sample code, you can build upon the knowledge gained with this book and use it in your own projects in the discipline of your choice.

Tips for program optimization

Next, let's take a look at some generic tips to optimize your programs.

Using filter and map

Python provides two built-in functions named filter and map to manipulate collections directly rather than having to iterate over each item in the collection. The filter, map, and reduce functions are faster than loops because a lot of the work is done by the underlying code written in C. The filter and map functions can be explained as follows:

  • The filter(function, list) function returns a list (iterators in Python 3.x) that contains all the items for which the function returns a true value. The following command is an example:

    print filter(lambda num: num>6, range(1,10))# prints [7, 8, 9]

    This is faster than running a conditional if-then check against the list.

  • The map(func, list) function applies func to each item in the list and returns the values in a new list (returns iterators instead of lists in Python 3.x). The following command is an example:

    print map(lambda num...
