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....

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

Fantastic course. This course and specialization so far are superbly taught and very enjoyable and I am learning the material well. I have two degrees from Michigan and the instruction in this course is as good, if not better, than what I have experienced even in the most excellent of courses in my prior experience. Great job!

Great comprehensive course. The code lense wouldn't work in all cases sadly, but that didnt' hurt much. It definitely worked for the pre-written examples. It was really helpful to see what is going on inside Python when dealing with dictionaries and functions.

I'd like to have more problem sets for practicing in my IDE though.

The course content is great and the instructors are brilliant because they can illustrate the course content to people with basic knowledge and make them understand every single detail. Thank you for explaining in a very simple way and giving us such assignments to check our understanding and engage us better in deep learning.

I've learned so much from this Phyton fundamental course. The assessment tests, exercises, the tools, such as codelens are just amazing. I'm off to a great start to learning the next in the 5-series specialization courses which is Data and Processing with Python. Kudos to the people who created this course. THANK YOU!

Of the courses I have taken so far, this one was one of the best. I almost did not watched the videos, only read and practiced using the book.

I was not 100% happy with the instructions provided to use google sheets on the last assignment. I think this should be improved, as many people may not have experience using it.

The course material is excellent and the way the Professors conveyed that is exceptional. I am thankful to coursera and University of Michigan for providing this learning plateform and assisting learners accros the globe. Now I am confident that I can prove myself on educational level and upcoming industry level.

The course goes on a prefect pace with great in depth insights and knowledge. Great instructors and course material with practice tools, interactive textbook, and exercises are the perfect way to learn programming. Many examples to follow through and sense of logical reasoning is also included for each examples.

I have always been scared of dictionary, mixing between tuple, list, etc...However, this course had changed everything. I'm so confident working with these type of data. Highly recomment this course, very details, a lots of exercises to practice, instruction is easy to understand and follow. Thank you all!

It is good course which covers Files and Dictionaries. I learnt about lambda expressions and how to use them as key in sorted function, through which I can specify the comparison criteria. The textbook was also good, providing all the key information. Overall it's a great course to learn more of python.

This course was a bliss to complete. I loved the way it takes you through the various concepts. The tutors make it so much happening that you will not feel bored about it, especially Paul Resnick's jokes, haha you can giggle for minutes .

Thanks to all the tutors and Coursera for making such a course.

I had very high expectations for this course after taking the first course in the sequence and a couple of Dr. Chuck Severance's courses. The combination of the online Runestone textbook with short videos and daily practice is fantastic. I look forward to my 5 practice questions every morning.

Well done. However, there were some Runestone lessons that were poorly worded as to the action required to achieve a passing score. Also, at least one of the lesson was flat wrong (according to the way the question was worded and the solution that resulted in a passing score).

A very well structured course that teaches you a lot of fundamental programming structures and how they are implemented with python. I learnt a lot on this course and it's been very helpful. Looking forward to use this course and move on to the next one on the specialization !

Final project will test you cumulative contents learned from the course 1. By this time, you probably know that copy and paste don't really help. Try not too much use google. Once you write project on your code, you , you will definitely feel like you have made a quantum jump.

I am so happy for that conquer. Seriously. I took Python classes at college, it wasn't that effective at all. I had so much advance on this course that I am very interested in getting more advanced python courses. Thank you, Coursera, and my colleagues and Michigan University.

Great course to follow the Python Basics course. The instructors have a great method of teaching and then reinforcing the basics in more advanced situations. I'm even surprising *myself* with some of the problems I've been able to solve and the code I've been able to write.

This is a great course. the explanations are clear, there are the interative page that allows us to run code and test many times what we have learned. I really like that the videos are not too long and we can do exercises watching them. I am learning a lot.

Continuing on the previous course, "Python Functions, Files, and Dictionaries" provides a solid introduction to handling files, dictionaries and functions, and also little nuances and quirks that are unique to Python. Well-paced, and extremely enjoyable.

It was a good course because of the concepts addressed, pretty much what the title says. The only constructive thing that I have to say is that the course can be improved by adding more challenging problems, because at some point they become repetitive.

I loved this class. They cover the material is a slow and methodical manner. The instructors are clear and concise in their lectures. I've learned a lot and look forward to finishing this specialization before moving on to more advanced Python classes.

This course is a great way to continue learning python. The lectures are well structured and the interactive book is one of the best tools I have seen for learning a new programming language. It is also not too intensive so it is very easy to complete.

The Runestone plateform is sometimes not working and the revision feature crashes a lot. Moreover, I wish there was a book to revise some things... other than that, it is a great course and you do learn a lot. The lecturers do a good job at explaining.

Things are getting more challenging and exciting with this 2nd course in the specialization. Topics build on previous lessons and apply them in more challenging ways. I'm really glad I took this series of courses to help me get the right skills I need

This course is well designed to give its learners the best learning experience. Every concept is explained in a simple manner with good examples. All of the tools available for reading and practicing have been really helpful throughout the course.
