Chapter 5. Higher-order Functions

A very important feature of the functional programming paradigm is higher-order functions. These are functions that accept functions as arguments or return functions as results. Python offers several of these kinds of functions. We'll look at them and some logical extensions.

As we can see, there are three varieties of higher-order functions, which are as follows:

  • Functions that accept a function as one of its arguments
  • Functions that return a function
  • Functions that accept a function and return a function

Python offers several higher-order functions of the first variety. We'll look at these built-in higher-order functions in this chapter. We'll look at a few of the library modules that offer higher-order functions ...
