没有,但是你可以创建一个类来处理它。基本上你需要覆盖 __getitem__ 方法,检查传递的值是否为元组,在这种情况下,将相应返回:

class MatlabList(list):
    def __init__(self, *args):
        if len(args) > 1:
            return super().__init__(args)
        return super().__init__(*args)

    def __getitem__(self, item):
        if isinstance(item, tuple):
            # Remove the non-needed tuple in case it onle has one element
            if len(item) == 1:
                return self[item[0]]
            if isinstance(item[0], slice):
                return MatlabList(map(lambda x: x[item[1:]], self[item[0]]))
            return self[item[0]][item[1:]]
        return super().__getitem__(item)

lst = MatlabList(
    MatlabList(111, 111, 4523.123, 111, 111),
    MatlabList(111, 111, 4526.15354, 111, 111),
    MatlabList(111, 111, 4580.112, 111, 111),
)

lst[1,2]  # cell at 2nd row, 3rd column
lst[1,:]  # 2nd row
lst[:,2]  # 3rd column
