About the Course

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....

The course met all my expectations and went beyond. The instructors' explanations were easy to understand and the innovative method of having a digital textbook was undoubtedly convenient.

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.

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

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.

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.

Excellent course, I believe one of the best in terms of Python explaining the use of functions in details, as well as common mistakes made during programming.
