dictionary_data = {'Changeable': 'Yes', 'Unordered': 'Yes', 'Duplicates': 'No'}
And as simplicity continues while learning Python, it's time to talk about a unique way of saving data in Python using something called DICTIONARY.
Dictionary is based on the principle of key-value
Like when you want to search for a word definition in the dictionary, you search for the word, in Python dictionaries you search for the KEY to get the VALUE.
Let's take a look at a basic syntax of a dictionary which represents a stored data for names and ages of two people:
names_ages = {'Oliver': 20, 'George': 23}
Oliver and George are the keys, 20 and 23 are the values.
Getting a value:
names_ages['Oliver']
will return 20.
Adding a new key and value:
names_ages['Michael'] = 24
Updating a value:
names_ages['Oliver'] = 30
Removing an entire element:
del names_ages['Oliver']
(Now Oliver the key and its value are removed)
If you want to print each pair separated by a comma you can use the items() method:
print(names_ages.items())
