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. Just like the cover's image, I want to take you to go up the stairs step by step and you also learn programming with Python by this way, step by step. I think you should slow down and experience what you should know about programming.
There are three parts of this e-book.
Part One - Basics
Part Two - Software Development
Part Three - GUI
Part One brings together all the basic skills about Python you need to know. Part Two introduces the basic knowledge about software development. Part Three designs a graphical user interface using Tk of the standard library.
The purpose of this e-book is an introduction about programming with Python. You may need two or three months to study this e-book.
The main reference of this e-book are the following web pages and books.
