How to use HashMap in Python

Question

I want to implement a HashMap in Python.

I want to ask a user for an input. Now, 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", "ABC");
   streetno.put("2", "DEF");
   streetno.put("3","GHI");
   streetno.put("4","JKL");
   streetno.put("5","MNO")

Answer 1

You can use Python dictionary it is a built-in type that supports key-value pairs.

streetno = {"1":"ABC", "2":"DEF", "3":"GHI", "4":"JKL","5":"MNO"}

as well as using the dict keyword:

streetno = dict({"1":"ABC", "2":"DEF"}) 

or:

streetno = {}
streetno["1"] = "ABC" 

This will help your need.
