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'])
