Dictionary in Python

Explain the dictionary in Python.

- Python's built-in data type is dictionary, which defines one-to-one relationships between keys and values.
- Dictionaries consist of pairs of keys and their corresponding values.
- Dictionaries are indexed by keys.
- Dictionary is similar to associative array or hash table of other languages.
- As following example explains further- India, Angel & Cartoon are keys & their corresponding values are Bharat, Mother Teresa & Mickey respectively.
>>> dict = {'India': 'Bharat', 'Angel': ‘Mother Teresa’, 'Cartoon': 'Mickey'}
>>>print dict[India]
Bharat
>>>print dict[Angel]
Mother Teresa

Dictionary definition is confusing and wrong
Dear Sirs;

You need to update your dictionary definition. Currently it reads:

"Dictionaries consist of pairs of keys and their corresponding values"

It should read-"Dictionaries consist of key, value pairs.

Your definition reads as if there are pairs of keys which is incorrect.
