Open Dictionary.py. Run->Run Module. In python shell type:

4.

5.

6.

>>> books.pop (111)

>>>

>>> books

>>> deleteditem = books.pop(2222)

>>> print (deleteditem)

>>> books

>>>

In the above example we have deleted the key-value pair for the key 111. You will see that the pop command prints the value for key 111; in other word the pop command returns the value for key 111 i.e. Black Beauty. In line 3 we print the contents of books dictionary to see the remaining items.
