# Data Structures

### Essentially, data structures are different ways of organizing data so that you can access, store, and use information effectively. 

In Module 1, you learned how to assign singular values to variables. In this module, you will learn how to store larger amounts of information inside data structures.

Some basic data structures that are useful in data science include: lists, dictionaries, and tables. In this module, you'll be learning how to use them to store data!
