Python的字符串的数组指数

问题描述

是否有可能在Python中使用字符串作为索引的数组？

例如：

  myArray的= []
myArray的[约翰] =嫖客值
myArray的[杰夫] =杰夫斯值
打印myArray的[约翰]
 

解决方案

您想要什么叫做。在蟒蛇这些被称为。

myDict = {}
myDict["john"] = "johns value"
myDict["jeff"] = "jeffs value"

Alternative way to create the above dict:

myDict = {"john": "johns value", "jeff": "jeffs value"}

Accessing values:

print myDict["jeff"] # => "jeffs value"

Getting the keys (in Python v2):

print myDict.keys() # => ["john", "jeff"]
