如何在Python中接受多维列表中的用户输入字符串？

my_list = [[], []]

for i in range(len(my_list)):
    for j in range(len(my_list[i])):
        user_input = input("请输入第{}行，第{}列的字符串：".format(i+1, j+1))
        my_list[i].append(user_input)

dimensions = int(input("请输入多维列表的维度："))
sizes = []
for i in range(dimensions):
    size = int(input("请输入第{}维的大小：".format(i+1)))
    sizes.append(size)

my_list = []
def create_list(dimensions, sizes):
    if dimensions == 1:
        return [[] for _ in range(sizes[0])]
    else:
        return [create_list(dimensions-1, sizes) for _ in range(sizes[0])]

my_list = create_list(dimensions, sizes)

for i in range(len(my_list)):
    for j in range(len(my_list[i])):
        user_input = input("请输入第{}行，第{}列的字符串：".format(i+1, j+1))
        my_list[i][j] = user_input
