        x.items()
                
        Output: 
          dict_items([(1, ‘abc’), (2, ‘def’), (3, ‘ghi’)])

  • Values() method: Returns a list of dictionary values. The syntax is: dict.values()
    y = {1:"xyz",2:"aeiou",3:"uvw"}
    y.values()
        Output: dict_values(['xyz', 'aeiou', 'uvw'])

  • Keys() method: Returns a list of dictionary keys. The syntax is: dict.keys()
    dict_one = {'animal': 'tiger', 'age':4, 'location':'Cage 5'}
   dict_one.keys()
     
    Output: dict_keys([‘animal’, ‘location’, ‘age’])
