Are any of the following ways of iterating over a list of lists better than the otheres (or even different)?

pets = [["Garfield", "cat", 4],
        ["Dog", "dog", 7.5], 
        ["Porkey", "pig", 61],
        ["Stoned", "rock", 0.230] ]


for name, species, weight in pets:
     print(name, species, weight)

for [name, species, weight] in pets:
     print(name, species, weight)

for (name, species, weight) in pets:
     print(name, species, weight)
