Return value

Returns a dictionary.

● Dictionary is another mutable container model and can store any type of object.

● Each key-value key=>value pair in the dictionary is separated by colon:. Each key-value pair is separated by comma,. The entire dictionary is included in curly braces {}. The format is as follows :

d = {key1 : value1, key2 : value2 }

The key is generally unique. If the last key-value pair is repeated, the previous one will be replaced. The value does not need to be unique.

>>>dict = {'a': 1, 'b': 2, 'b': '3'}
>>> dict['b']
'3'
>>> dict
{'a': 1, 'b': '3'}

The value can be of any data type, but the key must be immutable, such as string, number or tuple.

A simple dictionary example:

dict = {'Alice': '2341', 'Beth': '9102', 'Cecil': '3258'}

You can also create a dictionary like this:

dict1 = { 'abc': 456 }
dict2 = { 'abc': 123, 98.6: 37 }
