This course introduces the dictionary data structure and user-defined functions. You’ll learn about local and global variables, optional and keyword parameter-passing, named functions and lambda expressions. You’ll also learn about Python’s sorted function and how to control the order in which it sorts by passing in another function as an input. For your final project, you’ll read in simulated social media data from a file, compute sentiment scores, and write out .csv files. It covers chapters 10-16 of the textbook “Fundamentals of Python Programming,” which is the accompanying text (optional and free) for this course. The course is well-suited for you if you have already taken the "Python Basics" course and want to gain further fundamental knowledge of the Python language. Together, both courses are geared towards newcomers to Python programming, those who need a refresher on Python basics, or those who may have had some exposure to Python programming but want a more in-depth exposition and vocabulary for describing and reasoning about programs. This is a follow-up to the "Python Basics" course (course 1 of the Python 3 Programming Specialization), and it is the second of five courses in the specialization....

Finally, some challenge!

Sorting using anonimous lambda functions is awesome.

Final project is a bit confusing at start, because it supposes some independence (for the first time in a course I had to google some information). I think, it's a good practice, because in the end you become more confident in yourself.

Course is very easy for someone with some background in Python (or programming). What I didn't like is the fact the coding exercises are repeating themselves within one course. You can c/p and change a value to pass all exams... Another issue is the instructors answering all multiple questions or practice quizzes during the lecture videos. This does not allow someone to really practice, think and learn.

Incredibly well put together course from UMich. I found the content to be between entry and intermediate levels. All the efforts that went into the preparation of this course are much appreciated. All details that were optimized such as pacing, consistent practices, ideal difficulty, fun factor, subjects, articulate explanations etc. made a huge difference in the MOOC experience. Many thanks again!

The course is very sloppy. The negligence is just beyond my understanding. There are typos in the text. There are false statement in what is said (e.g. about some Windows operating system long ago not supporting long file names - Windows 3.1 wasn't an OS, and Windows 95 already supported them). There are obvious lapsus linguae in what is said. There are arrogant mistakes in TESTS! E.g.: it asks "sort-5-1: What will the sorted function sort by?

and says: "first country name (alphabetically), then temperature (lowest to highest)" but in the task script are "Reykjavik, Buenos Aires, Cairo, Berlin and Caloocan "

Since when Reykjavik, Buenos Aires, Cairo, Berlin and Caloocan are countries?!?

And it gets even more interesting in the next question! I.e. "sort-5-2: What how will the following data be sorted?" and among options:

A. first country name (reverse alphabetically), then temperature (lowest to highest)

C. first country name (reverse alphabetically), then temperature (lowest to highest)

The answers A and C are exactly the same. BUT! - The "A" is correct, while "C" is not!

And the microphone used within the specialization is very sensitive - so you hear them swallow every time. And since they are visibly uncomfortable being in front of a camera, they gulp down A LOT.

The course should be proof-read, proof-heard, the videos should be edited and the exams revisited. So far it is a disgrace to Coursera and american education.

I absolutely enjoyed this course. Not only did it help me gain an insight on Python files, dictionaries and functions, but it also helped me use these concepts smartly to create a project. A very well paced and well structured course. I would definitely recommend it to anyone interested in Python, and especially to those who have completed the first course of this Python specialization.

The course content and the instructions was awesome and the step by step approach of guidance in the project helped me a lot in the fact that I have learned how to approach any problems statements.

This course (and the specialization as well) is a bit more challenging than 'Python for Everybody'. I enjoyed a lot. Runestone is an amazing feature that really helped navigate through the course.

Good course, had a great hands on practice with the Runestone Notebook Environment.

Appreciate the efforts of the instructors and whoever has designed in making the course and helped delivering it.

This is the course to do because it makes use of spaced repetition learning - scientifically proven to be the best for recollection.

More in detail than e.g. Py4everybody but unfortunately everything has to be done in runestone.

Runestone is a nice tool but i would appreciate if students would be more encouraged to install python on their own computer and use an editor or IDE of their choice. You could at least provide the files used in runestone for practicing purposes.

The content is good, great even. I took one star off for the CONSTANT flipping back and forth between a short video (like 1-8 minutes) and their external resources. Give me an actual lecture, not a lecture tidbit. I took the second point off for the course ending with a "peer review" assignment that tested your ability to create a graph in excel (which is wholly outside the scope of this course) and seemed just plunked onto the end to ensure waiting time before you can "officially" finish the course because you're sitting around waiting for peer reviews on a project that required excel, not python, knowledge. I've got coursera pro so the delay didn't much hinder me, I just went to the next course - but I bet that peer review nonsense is a manufactured hurdle to thwart people trying to learn quickly on a 7 day trial. Pretty sleazy in my opinion.

The course material and videos are good, but it is impossible to get help from anyone from the University of Michigan if you have questions. You might get lucky and a fellow student may help, but if you want help from U of Michigan don't hold your breath.

This course and the balance of courses 1-4 of the specialization were fantastic - I would highly recommend each. Course 5 (the capstone project) was an abomination. Basically zero instruction / guidance and very frustrating for anybody except decently experienced programmers. If courses 1-4 are your only exposure to Python, you could easily spend a month or more on this project. If getting the Specialization Certificate is very important to you, there are resources online that you can leverage to complete the project but that is done largely at the expense of any real learning, so I really hope UofM comes up with an alternative final project that is more consistent with the level of expertise attained in courses 1-5 (maybe something on implementing classic algorithms?).

This is a great course, I've learned a lot from this course. What made this course great is that students could follow the instructors and do basic practises along the instruction. Lots and lots of basic practises solidified our learning. For example, all kinds of loops, string, list, dictionary etc handling take time to be proficient. You can understand these simple concepts by only watching videos, however, it takes lots of basic practices to really master. I took other python courses before, and I quickly forget everything because these courses lack the most critical part: many and many basic practices.

After all these practices and assignments, the final project looks like a piece of cake. Thank you UMich team. You guys are awesome!

Very good course. Good instructors and great production quality. The supplemental textbook is exceptional and adds far more value to the courses for those who choose to take advantage of it. Covers some of the more advanced areas of the Python language, and also shows some practical uses of these features. The final course project was interesting and that should provide a challenge but without being overly difficult.

My only complaint, similar to the previous course, is that other than the final assignment it's almost too easy. I wish students were challenged more because it's when you are pushed to your limits do you learn the most. But not worthy of knocking a star off the review, it's still excellent.

Excellent lessons, check your understanding, e-book, practice, and quiz work. This is not easy. You must know how to implement the instructions and be a bit clever as well. It is not perfect, but close enough.

Only issues are more suggestions. 1. To have a Show Me and then get a new questions, when you are stuck. The user blogs are only of minimal help. 2. To be precise in expectations - QA the requests for comprehension by students. I found expert reviews to be of marginal help as they all have assumptions.

The lectures did a good job of conveying the information contained in the interactive textbook beforehand and provided the learner with foundational information from which to apply and practice in the concept checks, assessments, and exercises. My only suggestion would be to include a section on writing and formatting csv files as this skill was necessary for the course project. Aside from that, I would highly recommend this course to anyone interested in beginning to learn how to code with Python.

Thorough, the video follows the reading almost exactly (reinforcement), and Runestone allows for tons of practice and repetition. I'm getting started on the next course in the series right away. I took this course as a free yearly course offered to students, and then took advantage of Coursera's 25% off discount for a Coursera Plus account, which this and many other courses are included in. Looking forward to more great content from UM (GO BLUE!) and Coursera! Thank you to all involved.

This course, which is a part of the specialization course, is one of the skillfully crafted courses. It equips learners with the very important conepts of python programming in a step wise approach. Also, it allows you to practise it through intesively in such a way that helps learners solidify their knowledge and practise. It is definately one of the best courses I have ever taken and would reccomend it to anyone who is committed to learn the course.

This course helps to understand how to use context manager to prevent you from forget to close files that are opened for write, nicely explains how you can iterate through files directly. It helps to understand why using a local variable inside a function is a good idea. Finally it helps to understand how to treat dictionaries and tuples. Overall, that's creates a great foundation for the subsequent course in the specialization. Very enjoyed.
