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.

TOP REVIEWS FROM PYTHON FUNCTIONS, FILES, AND DICTIONARIES
Very nice course, it could be a little bit challenging if you have no programming experience, but if you have done the past course and you put your attention you will definitely be able to pass it.
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.
Concept clarity provided by the amazing faculty is very good. The only areas of improvement would be in increasing the no of questions and also raising the difficulty of assessments.
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.
