商品描述

Master the art of writing beautiful and powerful Python by using all of the features that Python 3.5 offers

About This Book

  • Become familiar with the most important and advanced parts of the Python code style
  • Learn the trickier aspects of Python and put it in a structured context for deeper understanding of the language
  • Offers an expert's-eye overview of how these advanced tasks fit together in Python as a whole along with practical examples

Who This Book Is For

Almost anyone can learn to write working script and create high quality code but they might lack a structured understanding of what it means to be 'Pythonic'. If you are a Python programmer who wants to code efficiently by getting the syntax and usage of a few intricate Python techniques exactly right, this book is for you.

What You Will Learn

  • Create a virtualenv and start a new project
  • Understand how and when to use the functional programming paradigm
  • Get familiar with the different ways the decorators can be written in
  • Understand the power of generators and coroutines without digressing into lambda calculus
  • Create metaclasses and how it makes working with Python far easier
  • Generate HTML documentation out of documents and code using Sphinx
  • Learn how to track and optimize application performance, both memory and cpu
  • Use the multiprocessing library, not just locally but also across multiple machines
  • Get a basic understanding of packaging and creating your own libraries/applications

In Detail

Python is a dynamic programming language. It is known for its high readability and hence it is often the first language learned by new programmers. Python being multi-paradigm, it can be used to achieve the same thing in different ways and it is compatible across different platforms. Even if you find writing Python code easy, writing code that is efficient, easy to maintain, and reuse is not so straightforward.

This book is an authoritative guide that will help you learn new advanced methods in a clear and contextualised way. It starts off by creating a project-specific environment using venv, introducing you to different Pythonic syntax and common pitfalls before moving on to cover the functional features in Python. It covers how to create different decorators, generators, and metaclasses. It also introduces you to functools.wraps and coroutines and how they work. Later on you will learn to use asyncio module for asynchronous clients and servers. You will also get familiar with different testing systems such as py.test, doctest, and unittest, and debugging tools such as Python debugger and faulthandler. You will learn to optimize application performance so that it works efficiently across multiple machines and Python versions. Finally, it will teach you how to access C functions with a simple Python call. By the end of the book, you will be able to write more advanced scripts and take on bigger challenges.

Style and Approach

This book is a comprehensive guide that covers advanced features of the Python language, and communicate them with an authoritative understanding of the underlying rationale for how, when, and why to use them.

你將學到什麼

- 創建虛擬環境並啟動新項目
- 理解何時以及如何使用函數式編程範式
- 熟悉不同的裝飾器寫法
- 理解生成器和協程的威力,而不深入研究λ演算法
- 創建元類,並了解它如何使Python更容易使用
- 使用Sphinx將文件和程式碼生成HTML文檔
- 學習如何追蹤和優化應用程序的性能,包括內存和CPU
- 使用多進程庫,不僅在本地使用,還可以跨多台機器使用
- 基本了解打包和創建自己的庫/應用程序

詳細內容

Python是一種動態編程語言。它以其高可讀性而聞名,因此通常是新程序員學習的第一種語言。Python是多範式的,可以以不同的方式實現相同的目標,並且在不同平台上兼容。即使你發現編寫Python程式很容易,但編寫高效、易於維護和重用的程式碼並不那麼簡單。

本書是一本權威指南,將以清晰且有上下文的方式幫助你學習新的高級方法。它首先使用venv創建專案特定的環境,介紹不同的Python語法和常見問題,然後介紹Python的功能特性。它涵蓋了如何創建不同的裝飾器、生成器和元類。它還向你介紹了functools.wraps和協程以及它們的工作原理。之後,你將學習使用asyncio模塊進行異步客戶端和服務器。你還將熟悉不同的測試系統,如py.test、doctest和unittest,以及Python調試器和faulthandler等調試工具。你將學習優化應用程序性能,使其在多台機器和Python版本上高效運行。最後,它將教你如何通過簡單的Python調用訪問C函數。通過閱讀本書,你將能夠撰寫更高級的腳本並應對更大的挑戰。

風格和方法

本書是一本全面的指南,涵蓋了Python語言的高級功能,並以權威的理解傳達它們的基本原理,以及何時、如何和為什麼使用它們。
