To Vicki

When I began studying Python, I was impressed by how simple coding was and how easy it was to get started writing basic programs. I tried several development environments, and in all cases, I was able to get simple programs running in moments.

The Python syntax was simple, and there were no brackets or semicolons to remember. Other than remembering to use the Tab key (to generate those four-space indentations), coding in Python was easy.

But it was only after I played with Python for a few weeks that I began to see how sophisticated the language really is and how much you can really do with it. Python is a fully object-oriented language, making it easy to create classes that hold their own data without a lot of syntactic fussing.

In fact, I started trying to write some programs that I had written years ago in Java, and I was amazed by how much simpler they were in Python. And with the powerful IDEs, it was hard to make many mistakes.

When I realized how much I could get done quickly in Python, I also realized that it was time to write a book about powerful programs you can write in Python. This led to my writing new, clean, readable versions of the 23 classic design patterns that I had originally coded some years before.

The result is this book, which illustrates the basics of object-oriented programming, visual programming, and how to use all of the classic patterns. You can find complete working code for all these programs on GitHub at https://github.com/jwcnmr/jameswcooper/tree/main/Pythonpatterns.
