课程名称:使用Python访问网络数据 课程概述:本课程将展示如何将互联网视为数据源。我们将进行数据抓取、解析和读取网络数据,同时通过网络API访问数据。课程中将涉及HTML、XML和JSON数据格式的Python应用。该课程涵盖了《Python for Everybody》教材的第11-13章。为了顺利完成本课程,您应熟悉教材前10章的内容以及该专业化的前两门课程,包括变量和表达式、条件执行(循环、分支和错误处理)、函数、Python数据结构(字符串、列表、字典和元组)以及文件操作。本课程使用Python 3。 课程大纲: 1. 入门 - 描述:在此部分,您将安装Python和文本编辑器。在之前的课程中,这是一项可选作业,但在本课程中,它是开始的首要要求。从这一点开始,我们将不再使用基于浏览器的Python评估环境,因为它无法运行我们将在本课程中开发的更复杂程序。 2. 正则表达式(第11章) - 描述:正则表达式是一种非常专业的语言,允许我们简洁地搜索字符串并从字符串中提取数据。正则表达式是一种独立的语言。虽然不必掌握正则表达式的用法,但它们可以非常有用和强大。 3. 网络与套接字(第12章) - 描述:在这一部分,我们了解网络浏览器用来检索文档的协议以及网络应用程序与应用程序接口(API)交互的协议。 4. 互联网数据抓取程序(第12章) - 描述:在这一部分,我们学习如何使用Python从网站和API通过互联网检索数据。 5. 网络服务与XML(第13章) - 描述:在这一部分,我们学习如何检索和解析XML(可扩展标记语言)数据。 6. JSON与REST架构(第13章) - 描述:在本模块中,我们将使用JavaScript对象表示法(JSON)数据格式处理应用程序接口/网络服务。 此课程为希望深入了解如何通过Python有效获取和处理网络数据的学习者提供了全面的学习经历。
Name:Getting Started
Description:In this section you will install Python and a text editor. In previous classes in the specialization this was an optional assignment, but in this class it is the first requirement to get started. From this point forward we will stop using the browser-based Python grading environment because the browser-based Python environment (Skulpt) is not capable of running the more complex programs we will be developing in this class.
Name:Regular Expressions (Chapter 11)
Description:Regular expressions are a very specialized language that allow us to succinctly search strings and extract data from strings. Regular expressions are a language unto themselves. It is not essential to know how to use regular expressions, but they can be quite useful and powerful.
Name:Networks and Sockets (Chapter 12)
Description:In this section we learn about the protocols that web browsers use to retrieve documents and web applications use to interact with Application Program Interfaces (APIs).
Name:Programs that Surf the Web (Chapter 12)
Description:In this section we learn to use Python to retrieve data from web sites and APIs over the Internet.
Name:Web Services and XML (Chapter 13)
Description:In this section, we learn how to retrieve and parse XML (eXtensible Markup Language) data.
Name:JSON and the REST Architecture (Chapter 13)
Description:In this module, we work with Application Program Interfaces / Web Services using the JavaScript Object Notation (JSON) data format.
This course will show how one can treat the Internet as a source of data. We will scrape, parse, and read web data as well as access data using web APIs. We will work with HTML, XML, and JSON data formats in Python. This course will cover Chapters 11-13 of the textbook “Python for Everybody”. To succeed in this course, you should be familiar with the material covered in Chapters 1-10 of the textbook and the first two courses in this specialization. These topics include variables and expressions, conditional execution (loops, branching, and try/except), functions, Python data structures (strings, lists, dictionaries, and tuples), and manipulating files. This course covers Python 3.
