如何将二维数组中的每个元素除以一个值？(python)

def divide_array(arr, value):
    for i in range(len(arr)):
        for j in range(len(arr[i])):
            arr[i][j] /= value
    return arr

# 示例二维数组
array = [[1, 2, 3], [4, 5, 6], [7, 8, 9]]
# 除以的值
divisor = 2

result = divide_array(array, divisor)
print(result)

[[2, 4, 6], [8, 10, 12], [14, 16, 18]]

[[1.0, 2.0, 3.0], [4.0, 5.0, 6.0], [7.0, 8.0, 9.0]]
