In this chapter, we learned about regular expressions, using which we can define the rules for a set of strings that we want to match. We learned about the four functions of the re module: match(), search(), findall(), and sub().

We learned about the textwrap module, which is used for formatting and wrapping plain text. We also learned about the wrap(), fill(), dedent(), indent(), and shorten() functions of the textwrap module. Finally, we learned about the Unicode characters and how to print the Unicode strings in Python.

In the next chapter, we are going to learn about standard documenting and reporting of information using Python.
