This course builds upon the fundamentals of Python taught in Introduction to Python Programming and For Loops and Conditional Statements in Python. You’ll learn how to create Python dictionaries, which are important data structures in Python that help gather elements for identification using a key. You’ll also learn how to build frequency tables, which help to display the frequencies of different categories (particularly useful for understanding the distribution of values in a dataset). Finally, you’ll learn how to write Python functions, which will help you perform a single, related action on a specific set of data.
Best of all, you’ll learn by doing — you’ll practice and get feedback directly in the browser. You’ll apply your skills to several guided projects involving realistic business scenarios to build your portfolio and prepare for your next interview.
