如何在python中创建网格? [英] How do i make a grid in python?

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])

它不起作用，我也不知道为什么.这就是我放5个宽度和5个高度时得到的:

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

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

那很好，除了我使用以下方法更改左下角的点: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', '.', '.', '.', '.']

当行"列表被明确编码为不是 请帮助我解决该问题

It thinks the "row" list is a tag when it's clearly coded not to be Please help me on how to fix this problem

推荐答案

使用list()

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