Lean Python takes 58 Python methods and functions and whittles them down to 15: as author Paul Gerrard says, "I haven't found a need for the rest." What You'll Learn Discover lean Python and how to learn just enough to build useful tools Use Python objects, program structure, I/O, modules and more Handle errors and exceptions Test your code Access the Web; do searching; and persist data Who This Book Is For This book is aimed at three categories of reader: The experienced programmer – if you already know a programming language, this book gives you a shortcut to understanding the Python language and some of its design philosophy. You work in IT and need a programming primer – you might be a tester who needs to have more informed technical discussions with programmers. Working through the examples will help you to appreciate the challenge of good programming.
