Dictionary 

Dictionary data type is another feature in Python's hat. The dictionary is an unordered set of comma-separated key : value pairs, within {}, with the requirement that within a dictionary, no two keys can be the same (i.e., there are unique keys within a dictionary). For instance, following are some dictionaries : 

               {'a' : 1, 'e' : 2, 'i' : 3, 'o' : 4, 'u' : 5}

    >>>vowels = {'a' : 1, 'e' : 2, 'i' : 3, 'o' : 4, 'u' : 5}

    >>>vowels['a']

    1

     >>>vowels['u']

    5

Dictionaries shall be covered in details in a later Posts. 

Following figure summarizes the core data types of Python.
