CHAPTER 7. Functions

Defining functions using the def statement is a cornerstone of all programs. The goal of this chapter is to present some more advanced and unusual function definition and usage patterns. Topics include default arguments, functions that take any number of arguments, keyword-only arguments, annotations, and closures. In addition, some tricky control flow and data passing problems involving callback functions are addressed.
