The goal of this book is to teach you to think like a computer scientist. This way of thinking combines some of the best features of mathematics, engineering, and natural science. Like mathematicians, computer scientists use formal languages to denote ideas (specifically computations). Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions. The single most important skill for a computer scientist is problem solving. Problem solving means the ability to formulate problems, think creatively about solutions, and express a solution clearly and accurately. As it turns out, the process of learning to program is an excellent opportunity to practice problem-solving skills. That's why this chapter is called, The way of the program. On one level, you will be learning to program, a useful skill by itself. On another level, you will use programming as a means to an end. As we go along, that end will become clearer.

The Hitchhiker's Guide to Python takes the journeyman Pythonista to true expertise. More than any other language, Python was created with the philosophy of simplicity and parsimony. Now 25 years old, Python has become the primary or secondary language (after SQL) for many business users. With popularity comes diversity—and possibly dilution. This guide, collaboratively written by over a hundred members of the Python community, describes best practices currently used by package and application developers. Unlike other books for this audience, The Hitchhiker’s Guide is light on reusable code and heavier on design philosophy, directing the reader to excellent sources that already exist.

Python is an object-oriented programming. Its important philosophy is summarized by PEP 20. Like ◎ Beautiful is better than ugly. ◎ Explicit is better than implicit. ◎ Simple is better than complex. ◎ Complex is better than complicated. ◎ And so on.... The most important philosophy is "simple". So ◎ Keep it simple. When you write a Python program, the only thing you should keep in mind is the above sentence. But what is the meaning of "simple"? It is a good question, right? Simply speaking, the simple is a style and a thinking. That is to say, you should uses a direct, obvious and effective way to design a software using Python in any case. This e-book will take you to learn programming with Python.
