How To Get Key And Value From Dictionary In Python

Chapter: Python Last Updated: 24-05-2023 17:25:22 UTC

Program:

            /* ............... START ............... */
                
# Getting keys:
my_dict = {"a": 1, "b": 2, "c": 3}

# Get keys using keys() method
keys = my_dict.keys()
print(keys)




## Getting values:

my_dict = {"a": 1, "b": 2, "c": 3}

# Get values using values() method
values = my_dict.values()
print(values)




## Getting keys and values:
my_dict = {"a": 1, "b": 2, "c": 3}

# Get keys and values using items() method
items = my_dict.items()
print(items)

                /* ............... END ............... */
        

Output

Please find ouput of the three program above.

dict_keys(['a', 'b', 'c'])

dict_values([1, 2, 3])

dict_items([('a', 1), ('b', 2), ('c', 3)])


Notes:

  • First example, the keys() method is used to retrieve a view object containing all the keys of the dictionary. The view object can be converted to a list if needed, using the list() function.
  • Second example, the values() method is used to retrieve a view object containing all the values of the dictionary. Similar to the keys, the view object can be converted to a list using the list() function.
  • Third example, the items() method is used to retrieve a view object containing tuples of key-value pairs from the dictionary. Each tuple consists of a key-value pair enclosed in parentheses. Again, the view object can be converted to a list if desired.
  • You can iterate over the keys, values, or items using a for loop or perform other operations on them as per your requirements.
