Python dictionary values() usage and example

Python dictionary methods

The values() method returns a view object that displays a list of all values in the dictionary.

The syntax of values() is:

dictionary.values()

values() parameters

The values() method does not take any parameters.

values() return value

The values() method returns a view object that displays a list of all values in the given dictionary.

Example1：Get all values from the dictionary

#　Dictionary
sales = {　'apple':　2,　'orange':　3,　'grapes':　4　}
print(sales.values())

When running the program, the output is:

dict_values([2,　4,　3])

Example2：How does the values() work when modifying the dictionary?

#　Dictionary
sales = {　'apple':　2,　'orange':　3,　'grapes':　4　}
values = sales.values()
print('Original item:', values)
#　Delete an item from the dictionary
del[sales['apple']]
print('Updated item after update:', values)

When running the program, the output is:

Original item:　dict_values([2,　4,　3])
Updated item after update:　dict_values([4,　3])

The view object values itself does not return a list of sales item values, but returns a view of all values in the dictionary.

If the list is updated, the changes will be reflected in the view object itself, as shown in the above program.
