^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: Polygon.__init__() takes 2 positional arguments but 3 were given
错误原因：
图书源码文件draw2d.py中107行的Polygon构建函数与新版本的matplotlib代码不兼容
修正方式：
打开draw2d.py
找到第107行
poly = Polygon(object.vertices, True) 修改为 poly = Polygon(object.vertices)标签：__,given,.__,Polygon,py,draw2d,chapter3,pythonTest,wang From： https://www.cnblogs.com/wangpei/p/17769326.html
