Functional Programming Modules函数式编程模块

The modules described in this chapter provide functions and classes that support a functional programming style, and general operations on callables.本章描述的模块提供了支持函数式编程风格的函数和类，以及对可调用项的一般操作。

The following modules are documented in this chapter:本章记录了以下模块：

• itertools — Functions creating iterators for efficient looping函数创建迭代器以实现高效循环
  • Itertool functionsItertool函数
  • Itertools RecipesItertools配方
• functools — Higher-order functions and operations on callable objects可调用对象上的高阶函数和操作
  • partial Objects对象
• operator — Standard operators as functions标准运算符作为函数
  • Mapping Operators to Functions将运算符映射到函数
  • In-place Operators就地运算符
