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.
