In this module, you'll learn about different structures in Python. When you began learning Python for Data Science, you encountered two data structures: lists and dictionaries. While these are good for organizing data, there are many others and which one you choose depends on a few factors.
As this module progresses, we'll show you different types of data structures and what you need to consider when choosing the right one for your program.
Learning about data structures can be tough without any hands-on practice. That's why as you work through each concept, you’ll get to apply what you’ve learned from within your browser — there's no need to use your own machine to do the exercises. The Python environment inside of this course includes answer checking so you can ensure that you've fully mastered each concept before learning the next.
