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.

Getting Started
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.

Regular Expressions (Chapter 11)
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.

Getting a bit more challenging than the earlier courses in the specialization. The exercises require more struggle, but all the information is there. Another step along the way. Thank you, Dr. Chuck!

I have not found an easy way to learn how to code with python language. Mentor are really helpful and Dr Chuck is one of the most self explain professor that I have met in my three university career.
由 MP 提供Apr 7, 2016
This course is really very useful.The effort given by Dr.Chuck is very appriciateable and this course is very interesting as well because many great programmer told their history of discovered thing.

Challenging assignments, great teaching. I don't understand half of what these computer nerds are talking about, but I am figuring out how to complete their assignments. I must be learning something.
由 AS 提供Feb 13, 2020
It is a very good course even for an absolute beginner. Gives knowledge of what APIs, web scraping, different web protocols. Dr. Severence is engaging and very good at explaining hard things easily.
由 AG 提供Sep 12, 2017
The course teaches the basics of how to interact with the internet using Python. The course is simple, well explained, has great interviews with people who were part of the creation of the internet.
由 MF 提供Apr 15, 2019
need to write code step by step not to get usable code and explain it that's not interesting , writing the code from scratch is really exciting so please improve the course to be more enthusiastic .
由 SP 提供Oct 7, 2019
Very interesting course. Helped me solidify my understanding of SOA and APIs. I impressed my colleagues at an IT company for my understanding of these concepts. As an HR professional, this is gold.
由 HO 提供Jan 28, 2016
Dr. Chuck is so skilled at teaching. His teaching style and presentations are easy to follow. The class is not as challenging as other Python courses, but it's a great step to learning Python well.
由 ST 提供Mar 28, 2017
The course is very good. However the course covers only the basics of how to use python to access web data. It would have been good to add an assignment to use REST APIs in the real world scenario.
由 WW 提供Jun 25, 2016
Thanks for presenting the comprehensive introduction on not only python but the knowledge of the internet structure. And the plus interviewing videos with internet pioneers are really interesting.
