如何在二维数组中查找并打印搜索元素的位置(行和列)？

def search_element(matrix, target):
    positions = []
    for i in range(len(matrix)):
        for j in range(len(matrix[i])):
            if matrix[i][j] == target:
                positions.append((i, j))
    
    if len(positions) == 0:
        print("Element not found in the matrix.")
    else:
        print("Element found at the following positions:")
        for position in positions:
            print("Row:", position[0])
            print("Column:", position[1])

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

# 搜索元素 5
search_element(matrix, 5)

Element found at the following positions:
Row: 1
Column: 1
