【问题描述】：

我创建了这样的数组，

matrix = [[".",".",".",".",".",".",".",".",".",".","."],
      [" "," "," "," "," "," "," "," "," "," "," "],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."],
      [".",".",".",".",".",".",".",".",".",".","."]]

print('\n'.join([' '.join([str(cell) for cell in row]) for row in matrix]))

我想改变数组的元素。例如，当用户输入 0 2 之类的输入时，我想用“|”更改矩阵 [0][2]，我该怎么做？我知道如何获得输入我只是对更换零件感到好奇。

【问题讨论】：

可以阅读以下realpython.com/lessons/indexing-and-slicing
将问题中的“with”改为= 并将其放入您的代码中

标签： python arrays

【解决方案1】：

你可以使用这个sn-p：

def change(matrix, i, j, element):
    matrix[i][j] = element
    return matrix

您不需要函数来执行此操作！

【讨论】：

不需要函数，输入的不是新的矩阵值。
当然，这里是学习而不是生产的需要。所以它只是我提供的一个可用块......
虽然它不可用，但它不符合操作的要求。
