PYTHON练习题

题目1：假定有一个列表的列表，内层列表的每个值都是包含一个字符的字符串，像这样：

grid = [['.','.','.','.','.','.'],
        ['.','0','0','.','.','.'],
        ['0','0','0','0','.','.'],
        ['0','0','0','0','0','.'],
        ['.','0','0','0','0','0'],
        ['0','0','0','0','0','.'],
        ['0','0','0','0','.','.'],
        ['.','0','0','.','.','.'],
        ['.','.','.','.','.','.'],]

你可以认为 grid[x][y]是一幅“图”在 x、y 坐标处的字符，该图由文本字符组成。原点(0, 0)在左上角，向右 x 坐标增加，向下 y 坐标增加。复制前面的网格值，编写代码用它打印出图像。

...000...

....0....

答案：

grid = [['.','.','.','.','.','.'],
        ['.','0','0','.','.','.'],
        ['0','0','0','0','.','.'],
        ['0','0','0','0','0','.'],
        ['.','0','0','0','0','0'],
        ['0','0','0','0','0','.'],
        ['0','0','0','0','.','.'],
        ['.','0','0','.','.','.'],
        ['.','.','.','.','.','.'],]

for y in range(6):
    for x in range(10):
        if x == 9:
            print('\n')
        else:
            print(grid[x][y], end='')
