输出如下:
[('red', 'bike', 'big'), ('red', 'bike', 'small'), ('red', 'pencil', 'big'), ('red', 'pencil', 'small'), ('red', 'desk', 'big'), ('red', 'desk', 'small'), ('red', 'gun', 'big'), ('red', 'gun', 'small'), ('red', 'car', 'big'), ('red', 'car', 'small'), ('green', 'bike', 'big'), ('green', 'bike', 'small'), ('green', 'pencil', 'big'), ('green', 'pencil', 'small'), ('green', 'desk', 'big'), ('green', 'desk', 'small'), ('green', 'gun', 'big'), ('green', 'gun', 'small'), ('green', 'car', 'big'), ('green', 'car', 'small'), ('blue', 'bike', 'big'), ('blue', 'bike', 'small'), ('blue', 'pencil', 'big'), ('blue', 'pencil', 'small'), ('blue', 'desk', 'big'), ('blue', 'desk', 'small'), ('blue', 'gun', 'big'), ('blue', 'gun', 'small'), ('blue', 'car', 'big'), ('blue', 'car', 'small'), ('white', 'bike', 'big'), ('white', 'bike', 'small'), ('white', 'pencil', 'big'), ('white', 'pencil', 'small'), ('white', 'desk', 'big'), ('white', 'desk', 'small'), ('white', 'gun', 'big'), ('white', 'gun', 'small'), ('white', 'car', 'big'), ('white', 'car', 'small')]
即,itertools.product(list1,list2......listn),将list1到listn中的元素依次排列组合,返回一个新的list
