🖥️ Access Items from a Dictionary in Python (Get)
Dictionary elements must be accessible, somehow! If you do not get them by index, then how would you get them?
While indexing is used with other container types to access values, dictionary use keys. Therefore, values can be retrieved from a dictionary by specifying its corresponding key, in square brackets [].
my_dict = {
'age': 27,
'job': 'Youtuber',
'name': 'Digital Academy'
}
print(my_dict['name'])
OUTPUT: Digital Academy
○ Get Item from Dictionary in Python and avoid Exception
Nonetheless, If you refer to a key that is not in the dictionary, you will get an exception. To avoid such exception, you can use the special dictionary get() method. The difference while using get() is that it returns None, instead of KeyError, if the key is not found - and returns the value associated to its key, if key is in the dictionary.
Example: Try to print the value of the key ‘salary’
print(my_dict['salary'])
OUTPUT: KeyError: 'salary'
Example: Print values of the keys ‘name’ and ‘salary’
Key present
print(my_dict.get('name')) # OUTPUT: Digital Academy
Key absent
print(my_dict.get('salary')) # OUTPUT: None
