如何在python中制作网格?

问题描述

这是我的代码

width = int(input("How wide?"))
height = int(input("How high?"))
grid = []
row = []
bak = "."
for i in range(width):
    row.append(bak)
for i in range(height):
    grid.append(row)
while True:
    for i in range(len(grid)):
        print(grid[i])

它不工作，我不知道为什么.这是我放 5 宽和 5 高时得到的结果:

It's not working and i don't know why. This is what i get when i put 5 width and 5 height:

['.', '.', '.', '.', '.'] ['.', '.', '.', '.', '.'] ['.', '.', '.', '.', '.'] ['.', '.', '.', '.', '.'] ['.', '.', '.', '.', '.']

这很好，但当我使用以下命令更改左下角的点时:grid[0][0] = a".发生这种情况:

That's fine and all but when i change the bottom left dot by using this: grid[0][0] = "a". This happens:

['a', '.', '.', '.', '.'] ['a', '.', '.', '.', '.'] ['a', '.', '.', '.', '.'] ['a', '.', '.', '.', '.'] ['a', '.', '.', '.', '.']

它认为行"是list 是一个标签，当它被明确编码时不是.如何解决这个问题?

It thinks the "row" list is a tag, when it is clearly coded not to be. How to fix this problem?

解决方案

使用list()

gridline = [] for i in range(5): gridline.append("") grid = [] for i in range(5): grid.append(list(gridline))
