In this chapter, we went through the basics of Python programming, but we've also started to cover conceptually some of the fundamentals to create, store, and work with data. If you've made it this far, give yourself a pat on the back. You've successfully created your first program and learned the syntax of the Python programming language.

In the next chapter, you will take some of these principals to the next level to continue your data wrangling journey. I will talk first about modules, which allow you to add previously written code with additional functionality to our program. You will use modules to read from and write to different files, or conduct file I/O. I will cover the usage of for statements to iterate through the entries of a dataset, and basic methods to analyze and modify the data. Finally, I will cover functions that allow us to create blocks of code that we can run several times.
