Kotlin是否有“枚举"字样?像Python一样的功能? [英] Does Kotlin have an "enumerate" function like Python?

问题描述

在Python中，我可以写:

In Python I can write:

for i, element in enumerate(my_list):
    print i          # the index, starting from 0
    print element    # the list-element

我怎么用Kotlin来写这个?

How can I write this in Kotlin?

推荐答案

有一个

There is a forEachIndexed function in the standard library:

myList.forEachIndexed { i, element ->
    println(i)
    println(element)
}

也请参见 @ s1m0nw1的答案，withIndex也是迭代Iterable的一种非常不错的方法

See @s1m0nw1's answer as well, withIndex is also a really nice way to iterate through an Iterable.
