pag.95===> Na 2ª linha, alias recebe opposites com outra síntese. #28

                             ERRADO

                     >>> opposites = {’up’: ’down’, ’right’: ’wrong’, ’true’: ’false’}
                     >>> alias = opposities
                     >>> copy = opposities.copy() 

                             CERTO    

                     >>> opposites = {’up’: ’down’, ’right’: ’wrong’, ’true’: ’false’}
                     >>> alias = opposites
                     >>> copy = opposities.copy()


Ídem===>             alias[’right’] = ’left’
                     >>> opossites[’right’]
                     ’left’
