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....

This course was really interesting and did a good job introducing complicated topics in usefully simplified form. It was a pleasure to listen to the instructor and I got everything I wanted out of it.

Interesting course, I consider information about XML and JSON as very informative. I will continue specialization "Python For Everybody". Thanks for Dr. Chuck and everyone, who created this material.

Course started out with python 2.7 and then moved to python 3.x after the second week. Felt like I was paying for a Beta course. Assignment samples didn't match up for the xml parsing section... json code was provided.... spend hours getting beautiful soup to work then figured out they had switched the python version on me.... course forum was worthless

Course 1 and 2 of this specialization were much more effective and easy to understand. The assignments were really hard. Somehow completed them but didn't get enough knowledge. Many of the topics were not properly explained so became much difficult to pass the assignments. The difficulty level was really high this time.

I was unfairly accused of plagiarism just for post a code that was posted on an instructor because I had question about this code, now I have an average for 89.9 without this assestment and I cannot get the certificate just for this.

I am really disappointed by the teaching staff , I did not copy/paste any of the codes yet they have given me zero grades. This is how you examine student's code ? Because of this I feel so disappointed after all these efforts.

You can't get help. I got stuck on this one assignment. but the only place to get help is a forum which is not helpful. I was asking for extra help and that doesn't happen. This is strictly you get what you pay for.

Very hard course all of a sudden. I have completed many specializations and I can say that this has too steep a learning curve.

Very poor course... You can pass it in a one day even if you never program Python.

I often skip reading reviews of a course before enrolling as I often find "most useful reviews" being a bit harsh even if the average rate is near 5-stars. After I completed this course, I looked up the reviews and I was right about what I thought I was going to find. So the first thing that has to be addressed is that it's indeed true that this course feels a lot different from the previous two ones. But that's to be expected. The first two ones are too simple and too easy, so it doesn't come as a surprise that you get the feeling that they were better courses overall (as if the explanations were better and the assignments were more reasonable), because they were about simple things that were kept inside Python just to get used to this programming language, but this course is about interacting with other applications and languages without really explaining how they work. But explaining what exactly XML, JSON, API's. etc. are and how they work would take at least 1 course more for each one of them. So what can you expect when just 1 course covers all of these while still teaching you the basics of Python? It makes it feel rushed but that doesn't mean that it's bad. As Dr. Chuck has explained before, this specialization is about getting used to Python, getting to know what you can do with it rather than becoming a professional, so that then you can enroll in more courses about Python or other languages and not feel like you're completely lost and this course does that job perfectly. You still get a good idea about what those things are without deeply studying those subjects. Finall, the assignments are not just tweaking code but you also have to understand how they work, otherwise you would struggle even is most of the code is already written in the examples. You have to figure out a lot of things by yourself but it's not very difficult. You don't have to look up things on Youtube or Stackoverflow as others have stated, that's just exaggerating. Everything you need is in this course or in the provided book.

I just finished Using Python to Access Web Data, which is the third (3rd) course in the Python for Everybody specialization. The course wasn't so easy as the previous courses in the specialization as I had to spend more time debugging and practicing, nevertheless, it was lot more fun.

Completing and learning the coursework in this course would definitely have been impossible without the Python for Everybody team which includes the good Dr.Chuck and the mentors. There are many things I liked in this course. The discussion forums were great, the videos and slides were really cool and the mentors did great stuff like checking your code for you and other good stuffs. Becoming a programmer is subject to many constraints and the chiefest of this is the need for mentor-ship and the Python for Everybody team understands this so well.

There is just one flaw. I recommend more sample projects, more course work , more content, and more work files but this would make the course boring, last much more longer and nobody wants to grow grey hair learning python. The best way to take care of this might be to introduce an additional course. Notwithstanding,I give this course a 5-star rating and recommend it to anyone who has a thing for python and who has a good understanding of its syntax and data structures covered in the previous courses of the specialization.

This was a great learning experience. It was tough but in the end, you feel satisfied that you worked hard and your efforts paid off. Dr. Chuck is a great teacher, content creator and an inspiring technologist. I really enjoyed, apart from the core course content, his interviews of original creators such as the WWW, JSON, at the CERN centre etc. It helped me understand and empathise with myself when I found it difficult to grasp certain concepts.

I have one complaint though. The teaching staff (especially one Ms Tamara Brunnock) are nasty, rude towards beginner students like me and others. The discussion forums should be a courteous place to exchange thoughts and reveal your ignorances. However these teaching staff bully students with rhetorical questions. I don't know why they are teaching staff if they don't love the subject, love teaching and love interacting with students. I got zero value addition through these discussion forums. In some of these forums, there are external freelancers who help you out and that is the only help you get.

Beyond all this quibbling, Dr. Chuck is a great instructor and my computer knowledge is solely thanks to him.

As in the previous courses, the material was well explained and easy to follow. Dr. Severance is charismatic and makes the best of a less-than-ideal medium.

The assignments ended up being quite fun, but the wording is not always 100% clear, which I imagine poses some problems for those whose English isn't great.

The other thing is that the assignments were always more complicated than the examples shown. In some cases, it was possible to apply what we learned; in others, it was necessary to look up how to do certain things. That's not a problem, but expectations should be more clearly communicated because people will waste hours trying to modify code they were shown only to discover that there is a very specific way of writing something. It's akin to showing someone a few collocations in a foreign language and expecting them to intuitively know an idiom they've never seen before. However, for people who are barely learning how to code, assembling and adapting code is perfectly fine, as long as you understand exactly what everything does.

This has been an excellant designed course for everyone who is interested to become part of python programming course.

Dr. Chuck has been an expectional trainer throught out the course material and his method of explainning the slides while parallely informing that this particular content would help you resolve the 'Grade Exrecise' later down the course is simply awesome.

Once you finish the course,you would definately be in a position to understand from simple to medium complexity python programs.I would like to add one smart trick here "speciality of the course and explanation is the number of times you browse through the video material,more you will increase your understanding for that particular topic.

I can't thanks coursera and Dr. chuck enough to help people learning python so effectively and efficiently and making us build python community.

I began learning Python with this course. With absolutely no prior knowledge of or experience in Python (except lots of curiosity), I came across the first two courses on and loved Dr Charles' videos. It's a well structured course, especially if you have just started learning about Python and wish to build your skills more practically than by mere reading of numerous resources. There are plenty of resources that Dr Chuck (as he is fondly referred to by his students) offers in the duration of the course. I especially enjoy the bonus videos that accompany this course. They really help increase your knowledge base and urge you to know and be better and try your hand at various things. I'm glad I decided to pursue the entire specialization offered by University of Michigan, and it is all thanks to Dr. Chuck!

This is a wonderful course and a great tool to learn Python along with some obtaining some fundamental information about the Internet.The video lectures are very clear and accompanied by slides which elaborate the discussed topics. The course also presents a lot of bonus material including interviews. I love the lecturer who gives excellent explanations. My favourite moment was when after explaining the topic about the structure of the internet by a chart Dr. Charles Severance paused for a moment and breathed out heavily and said: "Actually it is easier (the topic) than it sounds". But, of course, his explanations were perfect, he is just passionate about transmitting the information to the students in the easiest to understand manner.And I have to say he succeeds admirably.Overall, I highly recommend this course

The course was rich and I learned so many things about web scraping, some regular expressions,parsing html, accessing web data and extracting information from the web, how data is exchanged between different softwares across the web and how to manipulate and parse this data if it was xml or JSON, and a brief introduction to service oriented architecture and what's an API and how to use APIs in your application to add a certain feature.

As always, Dr-Chuck is a great and an engaging instructor and I enjoy his lectures so much!

The only thing that I wished was more clear when I began this course is the exact curriculum and the exact skills that the learner should have by the end of it. I had to do a lot of researching and to thoroughly study the text book to achieve that. Other than that everything was 10/10!

This course is a good introduction to various aspects of web data. It's a pretty broad overview, so no one topic gets too much focus, but I feel much more informed about working with data from various web sources—how you get it, how it's formatted, and how to work with it once you've retrieved it. Dr. Chuck is a great teacher, and the assignments help you understand the material covered in the lectures through some hands-on work. One downside to this course as compared to the previous courses in the series is that the assignments seemed to involve more direct copying of example code, and less problem solving, which means it was harder to feel that I'd really mastered the techniques. That said, the materials provided are good examples and I'm sure I'll return to them in the future.
