How do i use dictionaries in python?
-
A dictionary is a key-value pair, defined using curly brackets.
>>> fruits = {'name' : 'orange', 'country' : 'spain'} >>> print(fruits) {'name' : 'orange', 'country' : 'spain'}
Add to a dictionary, here add group key to the fruits dictionary with value of citrus.
>>> fruits['group'] = 'citrus' >>> print(fruits) {'name': 'orange', 'group': 'citrus', 'country': 'spain'}
You can also nest dictionaries.
Define a nested dictionary.
>>> fruits = { 'oranges' : {'group' : 'citrus', 'country' : 'spain'}, 'apples' : {'group' : 'crunchy', 'country' : 'greece'}} >>> print(fruits) {'oranges': {'group': 'citrus', 'country': 'spain'}, 'apples': {'group': 'crunchy', 'country': 'greece'}}
Print difference dictionary values.
>>> print(fruits['oranges']['country']) spain >>> print(fruits['apples']['group']) >crunchy
