Java vs Python

Pythoni sõnastikud on sarnased Java "map"-idele.

HashMap<String, String> phoneBook =

                       new HashMap<String, String>();

phoneBook.put("Mike", "555-1111"); phoneBook.put("Lucy", "555-2222"); phoneBook.put("Jack", "555-3333");

  1. create an empty dictionary

phoneBook = {} phoneBook = {"Mike":"555-1111",

            "Lucy":"555-2222", 
            "Jack":"555-3333"}

  1. iterate over dictionary

for key in phoneBook:

   print(key, phoneBook[key])

  1. add an element

phoneBook["Mary"] = "555-6666"

  1. delete an element

del phoneBook["Mike"]

  1. get number of elements

count = len(phoneBook)

  1. can have different types

phoneBook["Susan"] = (1,2,3,4)

  1. return all keys

print phoneBook.keys()

  1. delete all the elements

phoneBook.clear() </syntaxhighlight>
