通过python中的索引访问字典值 [英] Accessing dictionary value by index in python

问题描述

我想通过Python字典的键索引来获取值。有没有办法得到这样的东西？

  dic = {} 
 value_at_index = dic.ElementAt ）
  

其中 index 是一个整数

PS问问题意味着缺乏一些理解，特别是如果它是一种新的语言，那么下降是什么，伙计？ （
ElementAt 广泛应用于C＃Linq

解决方案

标准Python字典本来就是无序的，所以你要求做的并不真实。

如果你真的知道你在做什么，使用

  value_at_index = dic.values（）[index] 
  

请记住，添加或删除元素可能会改变每个其他元素的索引。

I would like to get the value by key index from a Python dictionary. Is there a way to get it something like this?

dic = {}
value_at_index = dic.ElementAt(index)

where index is an integer

P.S. Asking question means lack of some understanding especially if it's a new language, so what the downvoting is for, buddies? :( ElementAt is widely used in C# Linq

解决方案

Standard Python dictionaries are inherently unordered, so what you're asking to do doesn't really make sense.

If you really, really know what you're doing, use

value_at_index = dic.values()[index]

Bear in mind that adding or removing an element can potentially change the index of every other element.
