交换二维数组中的两个元素

def swap_elements(array, row1, col1, row2, col2):
    temp = array[row1][col1]
    array[row1][col1] = array[row2][col2]
    array[row2][col2] = temp

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

# 交换第一个元素(1)和最后一个元素(9)
swap_elements(matrix, 0, 0, 2, 2)

print(matrix)

[[9, 2, 3],
 [4, 5, 6],
 [7, 8, 1]]
