Python中的哈希映射 [英] Hash Map in Python

问题描述

我想在Python中实现一个HashMap。我想要求用户输入。取决于他的输入，我从HashMap中检索一些信息。如果用户输入HashMap的键值，我想检索相应的值。

如何在Python中实现此功能？

  HashMap< String，String> streetno = new HashMap< String，String>（）; 
 streetno.put（1，Sachin Tendulkar）; 
 streetno.put（2，Dravid）; 
 streetno.put（3，Sehwag）; 
 streetno.put（4，Laxman）; 
 streetno.put（5，Kohli）

Python字典是一种内置类型，它支持键 -

  streetno = {1：Sachine Tendulkar，2：Dravid，3 ：Sehwag，4：Laxman，5：Kohli} 
  

以及使用dict关键字：

  streetno = dict（{1：Sachine Tendulkar，2 Dravid}）
  

或：

  streetno = {} 
 streetno [1] =Sachine Tendulkar
  

I want to implement a HashMap in Python. I want to ask a user for an input. depending on his input I am retrieving some information from the HashMap. If the user enters a key of the HashMap, I would like to retrieve the corresponding value.

How do I implement this functionality in Python?

HashMap<String,String> streetno=new HashMap<String,String>();
   streetno.put("1", "Sachin Tendulkar");
   streetno.put("2", "Dravid");
   streetno.put("3","Sehwag");
   streetno.put("4","Laxman");
   streetno.put("5","Kohli")

解决方案

Python dictionary is a built-in type that supports key-value pairs.

streetno = {"1":"Sachine Tendulkar", "2":"Dravid", "3":"Sehwag", "4":"Laxman","5":"Kohli"}

as well as using the dict keyword:

streetno = dict({"1":"Sachine Tendulkar", "2":"Dravid"}) 

or:

streetno = {}
streetno["1"] = "Sachine Tendulkar"
