Example

Remove single element

To remove the key/value pair for key 'height':


        
        
            
                
                
                    bob = {'age': 23, 'height': 180, 'hobby': 'surfing', 'fav_movie':'Forrest Gump'}

del bob['height']
print(bob)
                
            
            {'age': 23, 'hobby': 'surfing', 'fav_movie': 'Forrest Gump'}

Notice how the we have removed the key 'height' and its corresponding value.

Removing all elements

To remove all the key/value pairs from bob dictionary we can use the dict.clear() method:


        
        
            
                
                
                    bob = {'age': 23, 'height': 180, 'hobby': 'surfing', 'fav_movie':'Forrest Gump'}
bob.clear()
print(bob)
                
            
            {}
