                     PYTHON FUNCTIONS

                 Python provides various built-in functions. The following table describes these functions.


                                     Function                                 Explanation

                         sorted( )                          Sorts the elements

                         len( )                             Returns the length
                         cmp( )                             Compare items of the dictionaries

                         any( )                             Returns true if any of the dictionary item is true

                         all( )                             Returns true if all the dictionary items are true

                     UPDATING A DICTIONARY

                 You can easily add or modify the elements of a dictionary. If the item is present in the dictionary,
                 then you can change its value by providing new value to its key term.
                 Program 3: To update a dictionary.











                 On running the above program, you will get the following output:















                     REMOVING OR DELETING ELEMENTS OF A DICTIONARY

                 As you know, the pop( ) method is used to remove the dictionary element with the specified
                 key. The clear( ) method is used to remove all the elements of a dictionary and the popitem( )
                 method is used to remove any element from the Python dictionary. The del method is used to
                 delete a specific element or entire dictionary.
