for x in range(1,4): sea_creatures += ['fish'] print(sea_creatures)

Output ['shark', 'octopus', 'blobfish', 'mantis shrimp', 'anemone', 'yeti crab', 'fish'] ['shark', 'octopus', 'blobfish', 'mantis shrimp', 'anemone', 'yeti crab', 'fish', 'fish'] ['shark', 'octopus', 'blobfish', 'mantis shrimp', 'anemone', 'yeti crab', 'fish', 'fish', 'fish']

For each iteration of the for loop, an extra list item of 'fish' is added to the original list sea_creatures.

The *= operator behaves in a similar way:

sharks = ['shark'] for x in range(1,4): sharks *= 2 print(sharks)
