Question

嘿，伙计们，我是初级程序员，在这个特定的应用程序中遇到了麻烦。

我想从python-chess库中渲染一个棋盘，它总是返回一个SVG xml字符串而不是图像。这是文档python-chess

>>> chess.svg.piece(chess.Piece.from_symbol("R"))
'<svg version="1.1" viewBox="0 0 45 45" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"><g class="white rook" fill="#fff" fill-rule="evenodd" id="white-rook" stroke="#000" stroke-linecap="round" stroke-linejoin="round" stroke-width="1.5"><path d="M9 39h27v-3H9v3zM12 36v-4h21v4H12zM11 14V9h4v2h5V9h5v2h5V9h4v5" stroke-linecap="butt" /><path d="M34 14l-3 3H14l-3-3" /><path d="M31 17v12.5H14V17" stroke-linecap="butt" stroke-linejoin="miter" /><path d="M31 29.5l1.5 2.5h-20l1.5-2.5" /><path d="M11 14h23" fill="none" stroke-linejoin="miter" /></g></svg>'

我试图用svgwrite渲染这个但是无法做到。

在python中有没有其他方法我可以直接将所述XML呈现给图像并在屏幕上显示？

还尝试使用IPython.display模块尝试显示SVG，但它总是返回一个Object而不是图片。指导我正确的方向

非常感谢您提前

尝试Pygame。它不仅可以让您显示图像，还可以帮助您移动它们并与它们进行交互。如果你打算下棋，我相信Pygame会有所帮助！如果你真的想坚持SVG那么......我想我只是想帮忙。如果你想要一个示例代码，请在下面评论。希望这有帮助！

好的，我完成了。到目前为止，游戏允许您将棋子移动到允许的位置。但其余的我会留给你，因为这需要一点时间。如果您在pygame中需要任何指导，请再次发表评论，我会尽力提供帮助。这是代码：

import pygame, time, sys, random
from pygame.locals import *

# Initialize pygame (this is nessseccary for it to run all it's commands)
pygame.init()

# Draw the screen. The width and the height define how long and how wide the window is
width = 600
height = 500
window = pygame.display.set_mode((width, height))
TRANSwindow = window.convert_alpha()

# this sets the window title to "Chess!"
pygame.display.set_caption("Chess!")

# define some colours that we might need for later decoration
aqua = 0, 255, 255
black = 0, 0, 0
blue = 0, 0, 255
fuchsia = 255, 0, 255

yellow = 255, 255, 0


# Make a group that contains the sprite pieces that we need

                                        ClickSpaces.empty()

    window.fill(white)
    grid.draw(window)
    pieces.draw(window)
    ClickSpaces.draw(window)
    pygame.display.update()

复制代码并将其放入python后。保存项目，然后下载以下图像并将它们放在与代码相同的文件中：

返回SVG对象或XML字符串而不是Image
