What are Dictionaries in Python?

Dictionaries is an unordered collection of key value pairs.

How the dictionaries will look?

A dictionaries hold the key and values inside the curly braces where as key and values are separated by colon : operator..

Syntax:

VariableName={' key1 ' : ' value1 ', ' key2 ' : ' value2 ', .....' keyN ' : ' valueN ' }

Note Worthy: In Python dictionaries will be created by means of the Curly braces { } consists of key and values inside in it

eg: {'key' : 'values'}

Example:

Note: Use the 🖉 to see code editor. Use the ▶ view the output .

Explanation:

#line 1 : phones={'a':'apple','b':'blackberry', 'c':'celkon', 'n':'nokia', 's':'samsung'}
This is way by which dictionaries in python are created.

#line 3 : print phones
This line will print the elements(keys : values) present in the dictionaries.

#line 6 : print phones['a']
This line is used to print the elements in the dictionaries by means of their index values.

#line 9 : print phones.values()
This line is used to print the values present in the dictionaries by means of using the .value() function.

#line 12: print phones.keys()
This line is used to print the keys present in the dictionaries by means of using the .keys() function.
