课程概述

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....

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.

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!

So far courses 1 and 2 have been great with excellent explanations. I have no idea why, but that all changes for this course. The explanations are lacking and I'm left super confused. I ended up passing this class, but I feel I didn't get a good grasp and would need to take another "access web data" like class to actually have a grasp, even a basic grasp at that. This course should be revisited with better explanations.

Unfortunately on the whole I was very disappointed with this class. I took the first two Python courses and found them manageable, but this third one was an unrealistic increase in difficulty from the previous two. I reached out for help on the discussion board a number of times and saw many others were struggling as well. Mentors who responded to some of the other students were clearly getting defensive when those students were getting nowhere on the assignments. I think this program should reevaluate itself so students such as me can keep up with the assignments. On average I was spending about 10 hours per week just on the syntax for building the programs.

A little about my background: I have 20 years of experience in the private sector and am currently an analyst in cyber security. I have an undergraduate degree in finance, an MBA, and another master’s degree in Data Analytics. This 5 course program has been described and sold as beginner level, and given my background I should have handily been able to complete it, but that was definitely not the case. Normally I don’t leave feedback unless I feel strongly about something, so I hope you take it seriously. Thanks.

The assignments often go way beyond what is taught in the lectures or book. There was not a single assignment that I did not have to rely on reading tons of extra info from Overstack or other coding sites. I don't mind if the course is challenging, but it's challenging not because it's extremely difficult, but rather because it is testing things that weren't taught.

As an experienced programmer, I am unimpressed. The assignments cover a good set of tools; web i/o. I would introduce classes before getting into web i/o; this would emphasize critical coding habits of productive programmers: modularity and reusability. Also, variables and files are poorly named. Comments are lacking. The exercises don't ask students to program; they ask students to tweak (at most) the example programs. Students are instructed to disable security features without sufficient discussion of the risks involved. Overall, the presentation looks rushed and unpolished. Code looks like it was hobbled together until it worked and never edited for clarity. If someone I cared about wanted examples of good programming, I would tell them to avoid this.

One of the Great Course on web Data Accessing through Python.

Thank you for your friendly teaching method.

Great material, but it feels a bit rushed, covering as many topics as it does, in such a short amount of time.

Doing this course is not so much related to Python but to other computer engineering topics.

Network concepts are required, as well as knowing other programming languages such as HTML, XML or JSON, API or WebServices. Assignments require parsing webpages in HTML, XML or JSON, so knowledge of the same is needed. I would not pursue this course unless having strong knowledge about those topics

It is offered as part of a certification for people that know nothing about programming, so between course 2 and 3 there is a huge conceptual gap (going from loops, if-else and defining variables to HTTPS protocols, JSON and Service Layers). Keep your expectations right

Excellent, taught me a lot and the assignments were hard enough that I felt adequately challenged.

the course is good but i think one thing can make it prefect for beginners which is more practical exercises to make the student feel confident moving to the next lesson

This course was horribly explained. The XML and JSON chapters just went over my head. I had to go to youtube for better and logical explanations. Feels like the instructor is in a hurry to finish the course content and do something else in his life

In the previous courses all the assignments could be completed just through making a code with the parts that were explained in the videos, but it's slightly another thing in this one. In the second assignment there were included such things as SSL and one cannot make the task right without adding SSL in the code (SSL weren't among the course topics).

Nevertheless, the API part is the only one which I had troubles with, other ones are great as usual.

Very useful stuff. Glad to get exposure at a high level to both XML and JSON. Would prefer to get introduced to objects a bit earlier - and maybe a bit more brush-up on dictionaries as applied here -- but I am impressed how the examples are structured to help us easily unlock things through self-study.
