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 final project explanation is not complete. The peer reviewed part of the final project shouldn't be there. I think the peer reviewed part of the final project is not necessary to prove the acquired knowledge in this course.

The course went well until the final. There was content that was not taught in the class, but you were expected to know how to do it. I think the curriculum was fine and was content was interesting to go through.

The course is good and the material is good too. The peer review is useless and doesn't make any sense due you have to wait until other decided to pick your work what can be ages.

The course was very good, but the lack of support and the staff not answering our questions is unacceptable.
