pythonzellegraphics&;While循环
我正在尝试创建不重叠的矩形抽认卡,并将它们放置在Zelle Graphics中的随机位置。xMin和yMin是矩形左上角的坐标,xMax和yMax是矩形右下角的坐标。我尝试生成随机(xCenter,yCenter)坐标来创建一个新矩形,并检查新矩形是否与任何现有矩形重叠。如果重叠,则生成新的随机点,直到不再重叠 我得到了检查重叠的函数,但之后我在while循环中遇到了问题。我是Python初学者,非常感谢您的帮助pythonzellegraphics&;While循环,python,while-loop,zelle-graphics,Python,While Loop,Zelle Graphics,我正在尝试创建不重叠的矩形抽认卡,并将它们放置在Zelle Graphics中的随机位置。xMin和yMin是矩形左上角的坐标,xMax和yMax是矩形右下角的坐标。我尝试生成随机(xCenter,yCenter)坐标来创建一个新矩形,并检查新矩形是否与任何现有矩形重叠。如果重叠,则生成新的随机点,直到不再重叠 我得到了检查重叠的函数,但之后我在while循环中遇到了问题。我是Python初学者,非常感谢您的帮助 from graphics import * from random import
