Summary

To summarize, recall that Python data structures include lists, tuples, dictionaries, and sets. Python provides these structures to enable you to code better as a developer. In this chapter, we covered lists, which are one of the most important data types in Python since they can store multiple objects, as well as other data types, such as dictionaries, tuples, and sets. Each of these data types helps us store and retrieve data effectively.

Data structures are an essential part of all programming languages. Most programming languages only provide basic data types for storing different types of numbers, strings, and Booleans, as you learned in Chapter 1, Python Fundamentals – Math, Strings, Conditionals, and Loops. They are an essential part of any program. In this chapter, you learned that lists and dictionaries may be used to store complex data, including nested lists and mixed data types.

In the next chapter, you are going to learn how to use functions to write modular and understandable code that follows the Don’t Repeat Yourself (DRY) principle.
