拆分阵列成红宝石多个小数组的最佳方法 [英] Best way to split arrays into multiple small arrays in ruby

问题描述

什么是阵列分成基于某些条件下多个阵列最简单的方法？在我的方案，我需要移动整数，字符串值不同的阵列。我曾尝试拆分方法，但并不如预期正常工作。

What is the simplest way to split arrays into multiple arrays based on some conditions? In my scenario, I need to move the integer and the string values to different arrays. I have tried split method, but does not work as expected.

x=[1,2,3,"a","b",4]
x.split {|item| item.kind_of? Fixnum}

在C＃中，有一个按选项的LINQ 的基础上，它可以帮助您组对象条件。是否有关于对象（不使用ActiveRecord）？

In C#, there is a group by option in Linq, which helps you group the objects based on the conditions. Is there a similar method on Object (not using activerecord) ?

有一个简单的方法是什么？

Is there a simple way?

推荐答案

您正在寻找的Enumerable#partition:

x = [1, 2, 3, "a", "b", 4]
numbers, not_numbers = x.partition{|item| item.kind_of?(Fixnum)}
# => [[1, 2, 3, 4], ["a", "b"]]
