The syntax of items() method is:
dictionary.items()
The items() method is similar to dictionary's viewitems() method in Python 2.7
items() Parameters
The items() method doesn't take any parameters.
Return value from items()
The items() method returns a view object that displays a list of a given dictionary's (key, value) tuple pair.
Example 1: Get all items of a dictionary with items()
# random sales dictionary
sales = { 'apple': 2, 'orange': 3, 'grapes': 4 }
print(sales.items())
When you run the program, the output will be:
dict_items([('apple', 2), ('orange', 3), ('grapes', 4)])
Example 2: How items() works when a dictionary is modified?
# random sales dictionary
sales = { 'apple': 2, 'orange': 3, 'grapes': 4 }
items = sales.items()
print('Original items:', items)
# delete an item from dictionary
del[sales['apple']]
print('Updated items:', items)
When you run the program, the output will be:
Original items: dict_items([('apple', 2), ('orange', 3), ('grapes', 4)])
Updated items: dict_items([('orange', 3), ('grapes', 4)])
The view object items doesn't itself return a list of sales items but it returns a view of sales's (key, value) pair.
If the list is updated at any time, the changes are reflected on to the view object itself, as shown in the above program.
