Learn Python the Hard Way (3rd Edition)

Learn Python the Hard Way (3rd Edition) is the Chinese edition of Zed A. Shaw's Learn Python the Hard Way, a Python primer for readers with no prior programming experience. The book does not organize itself around theory; instead it builds the learning path from 52 carefully designed exercises. The first 26 cover the basics—printing, input, variables, math, strings, and functions—while the remaining 26 move on to conditionals, loops, lists, dictionaries, modules, classes and objects, inheritance and composition, automated testing, handling user input, and simple websites and web games. Each exercise follows roughly the same format: the code and instructions are given, the reader types the code in character by character (copy-pasting is forbidden), runs the program and checks the output against the expected result, then completes the extra credit and reads the frequently asked questions. Through repeated typing, making mistakes, and debugging, the author wants beginners to understand how programs actually work, what good code looks like, and how to locate and fix errors the way a programmer does. The book ends with "The Next Steps," "Advice from an Old Programmer," and a command-line crash course, so readers can go further once they have the basics.
