when began studying pythoni was impressed by how simple coding was and how easy it was to get started writing basic programs tried several development environmentsand in all casesi was able to get simple programs running in moments the python syntax was simpleand 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 played with python for few weeks that began to see how sophisticated the language really is and how much you can really do with it python is fully object-oriented languagemaking it easy to create classes that hold their own data without lot of syntactic fussing in facti started trying to write some programs that had written years ago in javaand was amazed by how much simpler they were in python and with the powerful idesit was hard to make many mistakes when realized how much could get done quickly in pythoni also realized that it was time to write book about powerful programs you can write in python this led to my writing newcleanreadable versions of the classic design patterns that had originally coded some years before the result is this bookwhich illustrates the basics of object-oriented programmingvisual programmingand how to use all of the classic patterns you can find complete working code for all these programs on github at pythonpatterns this book is designed to help python programmers broaden their knowledge of object-oriented programming (oopand the accompanying design patterns qq qq qq if you are new to python but have experience in other languagesyou will be able to charge ahead by reviewing through and then starting back at if you are experienced in python but want to learn about oop and design patternsstart at if you likeyou can skip and and go right through the rest of the book if you are new to programming in generalspend some time going over through to try some of the programs then start on to learn about oop and design patterns you will likely find that python is the easiest language you ever learnedas well as the most effortless language for writing the objects you use in design patterns you'll see what they are for and how to use them in your own work in any casethe object-oriented programming methods presented in these pages can help you write bettermore reusable program code
