About the Course

This course teaches you to fetch and process data from services on the Internet. It covers Python list comprehensions and provides opportunities to practice extracting from and processing deeply nested data. You'll also learn how to use the Python requests module to interact with REST APIs and what to look for in documentation of those APIs. For the final project, you will construct a “tag recommender” for the flickr photo sharing site. The course is well-suited for you if you have already taken the "Python Basics" and "Python Functions, Files, and Dictionaries" courses (courses 1 and 2 of the Python 3 Programming Specialization). If you are already familiar with Python fundamentals but want practice at retrieving and processing complex nested data from Internet services, you can also benefit from this course without taking the previous two. This is the third of five courses in the Python 3 Programming Specialization....

This was a really excellent course. The functional project at the end helped me understand how recommendation systems work and now I'm very excited to try to build a similar system for books I love.

Very interesting and fine course, in this course I learn how to solve Nested data and new a new thing i.e REST API which seems best in course 3 now I am excited about course 4. Thanking you Michigan

The title is misleading, you only learn how to collect data from the API's in this course. For a course called data collection, we don't have much practice collecting data except the final project. The course is good if you are here to get a basic understanding of the subject and already posses some elementary programming knowledge. The online textbook is nice (It automatically grades assignments and provides instant feedback) however, for me, the daily practice exercises always comes from the first specialization course. Furthermore, if you accidentally click out of the page or time out while doing the final assignment the online textbook doesn't save your answers so you have to start over.

Loved the course. I learned a great deal. Now I need practice to review all the topics. My only complaint would be the final project. The whole requests_with_caching thing was a mess. I would recommend that you just have students obtain the api keys necessary and then write the code with requests. Also, I spent hours trying to work out why I was getting errors when I needed to use http instead of https. https was used in all the examples so students would obviously use https. That one cost me a lot of time and despair.

I would have given this course a 5-star review. However, I feel this is the time when the students should also be exposed to full Python environment through one of the IDE's and not just Runestone. Things need to get real and I still do not have 100% confidence in venturing out in the real world applications. I had downloaded a well known IDE in parallel to Course 3- Week 3 runestone. Although my Runestone environment practice and progress are fast, I am feeling miserable in the standalone IDE.

The course is very useful for beginners. I learned a lot of new things although not 100% especially after completing the project course. But still I would say close to 80-90% of the material. The project course had a good content but the bugs made it a mess. It was frustrating at times. So, I am giving it a 4 star or else I am thankful to the professor for teaching the content in a very lucid manner. I hope for more intense courses on python in the future.

First 2 weeks of the course were great but week 3 was confusing, boring, and with a lot of text and not enough practice. It took me a while to find strength and go though final assignment. It was painful experience since Runestone interactive is not suited for debugging very well and this assignment required a lot of debugging. Anyway, I am happy I am done with it and moving on to a next course of this Specialization.

I would appreciate it if the Course held your hand less. In the final project I should have had to figure out how to make the ranking program on my own without being walked through the steps. The global logic is often more difficult then getting the functions to work and I feel like i'm not prepared for writing programs on my own that have more than a couple lines.

Other than that it was great.

The Final Project, should not be based on a module that is not standard in Python. I ran the project with the standard module (requests) and it went fine. But when I try to do it with the non-standard module (requests_with_caching) things went south because I had to find-out how it worked, what the parameters were, and so on, with NO-DUBUG tool. Horrible!!

The testing in the final project was really confusing as the same code got correct answers in some questions and not in others. Particularly frustrating was the tests that called a function in the function being tested. This was super hard to debug as the error messages prevented me from seeing what input was being used by Runestone's testing.

The only reason I don't give this course 5 stars is some of the limitations of the Runestone learning environment. There were times I wished I could run some of the code in a seperate environment for troubelshooting and practice but for some exercises this wasn't possible. However, overall I found the course to be excellent.

The final on this one was a mess. You could not move the code out of runestone and it was impossible to step through in codelens. So, if you got stuck, good luck getting past it. I really enjoyed the assignments and videos, super helpful. Just didn't like the final.

This is overall an excellent course, although the last assignment was significantly more difficult than the assignments in the previous courses. Also, Skulpt posed a problem because it has limited imported ability. But I would still very much recommend this course!

Introduces you to using APIs, JSON data, and ZIP files - however, I felt it stopped a bit short of dealing with complex APIs. The example APIs used were fairly simple. Would have liked to see the use of some more complex use of APIs to build practical applications.

The course was wonderful. But there were too many errors while getting feedback after submitting the answers in final assignment. This problem should be resolved as the students do not get the correct feedback after attempting the task in the final assignment

I found the API portion of the course difficult. I think we should have had more interactive exercises to better prepare for the final exercise. I felt it was rushed. This could have been a four-week course. Having said that, I learned a great deal.

The videos were very detailed and step by step. The final project was challenging. You had to apply a lot of knowledge and sometimes there were effects in the Runestone environment that I couldn't explain. I am proud that it worked out in the end.

Great insight into obtaining data from the internet, however, a few functions could have been explained better for use in the final project. Nevertheless, by the end of the course I feel confident about the use of APIs and nested data structures

i loved this course , i learned many things . but week 3 about APIs it was strange to me , there's no enough exercises to solve or problems just final project , maybe because i don't know enough knowledge APIs

but anyway this course is awesome

the course is excellent .. but my personal point of views is that is should have some more wide variety of question so that students can practice more question and more varieties of question .. but at the end the coerces is excellent

it is an amazing course with hands on practice assignments. professor teaches in a very interesting and understandable way and makes things fun.

the objectives of this course were made very clear and were completely met at the end.

The class has great content or real-world use, and would easily get five stars if not for the final project having what seemed to be significant variation in data being returned by an API. It was causing the autograding to fail.

Great course. Last question was challenging. I couldn't recall that there was a little tidbit in the tie breaking sort video/reading from the last course. Eventually I saw that and it clicked but I totally forgot about it.

The course material is OK. The instruction for API session is bit rushed, but I learned a lot more than I expected after spending more time than I expected by repeatedly troubleshooting the coding in the final project.

A huge improvement from the two previous courses of the specialisation. Lecture time is more normalised, assessments not always the same or solved in the preceding video and more challenging graded assessments.

All in all, I really liked the course . I feel like the part about the caching and the module that was provided could be done better than that so student themselves could get involved with making that module.

Final assignment is not working as expected , there is some bug in runestone interactive page and therefore there is an invalid error being thrown and I am unable to finish this module because of this bug
