Functional Programming Modules

The modules described in this chapter provide functions and classes that support a functional programming style, and general operations on callables.

The following modules are documented in this chapter:

• itertools — Functions creating iterators for efficient looping
  • Itertool Functions
  • Itertools Recipes
• functools — Higher-order functions and operations on callable objects
  • partial Objects
• operator — Standard operators as functions
  • Mapping Operators to Functions
  • In-place Operators
