map()函数的输入是一个函数function以及一个或多个可迭代的集合iterable,在Python 2.x中map()函数的输出是一个集合,Python 3.x中输出的是一个迭代器。map()函数主要功能为对iterable中的每个元素都进行function函数操作,并将所有的返回结果放到集合或迭代器中。function如果是None,则其作用等同于zip()。
The array_reduce() function sends the values in an array to a user-defined function, and returns a string. Note:If the array is empty and initial is not passed, this function returns NULL. Syntax array_reduce(array, myfunction, initial) ...
