根据二维数组的内容检查值

def check_value(matrix, value):
    for row in matrix:
        if value in row:
            return True, (matrix.index(row), row.index(value))
    return False, (-1, -1)

# 示例二维数组
matrix = [
    [1, 2, 3],
    [4, 5, 6],
    [7, 8, 9]
]

# 检查值
value_to_check = 5
found, position = check_value(matrix, value_to_check)

if found:
    print(f"值 {value_to_check} 在位置 {position}")
else:
    print(f"值 {value_to_check} 不在数组中")

def safe_check_value(matrix, value):
    for i, row in enumerate(matrix):
        if value in row:
            return True, (i, row.index(value))
    return False, (-1, -1)

def check_value(matrix, value):
    if not matrix or not matrix[0]:
        return False, (-1, -1)
    for row in matrix:
        if value in row:
            return True, (matrix.index(row), row.index(value))
    return False, (-1, -1)
