Methods and Functions

Python Dictionary Items () 

A dictionary in Python is an unordered collection of items. As in a real-life dictionary, each word is associated with its meaning, in the Python dictionary, each key is paired with its respective value. Thus, the data in the dictionary is stored in pairs of key and value. 

Syntax to create a dictionary: name of dictionary = {key:value}

The items, that is, the data that is stored in the dictionary are unordered and mutable. Thus, they can be changed after the creation of the dictionary. However, the items cannot be duplicated within the same dictionary. These items can be of any data type, including numeric and characters such as integers, strings, floats, complex numbers. Boolean type, etc.   

Items () Parameters 

The items () method in the dictionary is used to return each item in a dictionary as tuples in a list. Thus, the dictionary key and value pairs will be returned in the form of a list of tuple pairs. 

Syntax of items () method: dictionary_name.items ()

The items () method does not take any parameters. 

Return Value from items ()

When you use the items () method on a dictionary, the key and value pair stored in it will be displayed in the form of tuples in a list. Note that the returned list is a view of the items stored in the dictionary. The method does not change a dictionary into a list. Also, all the changes that will be done in the dictionary will be shown in the list view as well.

Example 1: Get all items of a dictionary with items ()

                    

my_dict = {“fruit”: “apple”, “vegetable”: “potato”, “price”: 60} 

x = my_dict.items ()

print (x)

Output:

                    

dict_items ([(‘fruit’, ‘apple’), (‘vegetable’, ‘potato’), (‘price’, 60)])

Example 2: How items () works when a dictionary is modified?

                    

my_dict = {“fruit”: “apple”, “vegetable”: “potato”, “price”: 60} 

x = my_dict.items ()

print (x)

my_dict [“price”] = 70

print (x)

Output:

                    

dict_items ([(‘fruit’, ‘apple’), (‘vegetable’, ‘potato’), (‘price’, 60)])

dict_items ([(‘fruit’, ‘apple’), (‘vegetable’, ‘potato’), (‘price’, 70)])
