Python Functions, Files, and Dictionaries

This course introduces you to the dictionary data structure as well as user-defined functions. Learn about global and local variables, optional and keyword parameters-passing, named function and lambda expressions. Learn about Python's sort function, and how to change the order it sorts using an input function. Your final project will require you to read in simulated social data from a file and compute sentiment scores. This chapter covers the chapters 10-16 of "Fundamentals of Python Programming," the optional and free companion text for this course.

If you've already completed the "Python Basics", this course will be a good fit for you. Both courses are designed for newcomers to Python programming. They also provide a refresher course on Python basics. This course is a continuation of the "Python Basics", which is course 1 in the Python 3 Programming Specialization. It is the second of five courses.
