Python Essential Reference 4th 原版PDF by Beazley

This book is intended to be a concise reference to the Python programming language. Although an experienced programmer will probably be able to learn Python from this book, it’s not intended to be an extended tutorial or a treatise on how to program. Rather, the goal is to present the core Python language, and the most essential parts of the Python library in a manner that’s accurate and concise.This book assumes that the reader has prior programming experience with Python or another language such as C or Java. In addition, a general familiarity with systems programming topics (for example, basic operating system concepts and network programming) may be useful in understanding certain parts of the library reference.
