17.14    Built-In Functions

In the course of this book, we’ve often referred to built-in functions. These are predefined functions that are available to the programmer at any time. For example, you already know the built-in len and range functions. In this section, we’ll describe a selection of built-in functions in detail (see Table 17.1).
