高阶函数(High-order Function)是函数式编程中非常重要的概念,它是提升代码抽象层次的重要方法和手段。越来越多的语言开始支持函数式编程的范式,比如Java、C++。 虽然Python不是像Haskell这样纯粹的函数式编程语言,但是它也具有函数式编程的一些特性;而且Python现在应用非常广泛,了解一些这方面的特性,可以帮助我们写出更加...
reduce(add, [1, 3, 5, 7, 9]) = 25 当然求和运算可以直接用Python内建函数sum(),思考:如何把序列[1, 2, 3, 4, 5]转化为整型的 12345 ,下面给出代码但请尽可能自己先写出 View Code 思考:假如python没有提供int()函数,如何使用map与reduce自己写一个函数,实现将'123456'转化为123456,下面给出代码...
#很多初学者会混淆这两种赋值,通过Python内建的type函数,可以查看一下这两次赋值的结果:In [4]: type(ref1) Out[4]: function In [5]: type(ref2) Out[5]: str#可以看到,ref1引用了函数对象本身,而ref2则引用了函数的返回值。 #通过内建的callable函数,可以进一步验证ref1是可调用的,而ref2是不可调...

According to the five elements of the MDP (decision stage, state set, decision set, transfer probability, and reward), the MDP model in the production cycle is established, and the objective function is solved. Decision stage T It refers to any production time T in the production cycle, tha...
