About Lesson
Python dictionary is an unordered collection of items. In a dictionary, each item has a key/value pair.
Example:
users = {'name':'Junaid', 'age':25} print(users) print(type(users)) # access data from dictionaries print(users['name']) user_info = { 'name' : 'Junaid Shaikh', 'age' : 24, 'skills' : ['a', 'v'], 'tunes' : ['t', 'tv'], } print(user_info['skills'])
