无法将扫描的字符串正确输入到2D数组中

def parse_string_to_2d_array(input_string):
    # 解析字符串，获取元素信息
    elements = input_string.split(',')

    # 创建2D数组
    rows = 3
    cols = 3
    array_2d = [[0] * cols for _ in range(rows)]

    # 输入元素值到2D数组中
    for element in elements:
        position, value = element.split(':')
        row, col = map(int, position.split('-'))
        array_2d[row][col] = int(value)

    return array_2d

# 示例输入字符串：'0-0:1,0-1:2,0-2:3,1-0:4,1-1:5,1-2:6,2-0:7,2-1:8,2-2:9'
input_string = input("请输入扫描的字符串：")
array_2d = parse_string_to_2d_array(input_string)
print(array_2d)
