《程序员数学：用Python学透线性代数和微积分》第3.5章，源码bug修正。
报错信息：
wang@wanggongdeMacBook-Air pythonTest % /usr/local/bin/python3 /Users/wang/Docum ents/VSCode/pythonTest/chapter3/chapter3.py Traceback (most recent call last): File "/Users/wang/Documents/VSCode/pythonTest/chapter3/chapter3.py", line 196, in <module> render(octahedron, color_map=matplotlib.colormaps.get_cmap('Blues'), lines=black) File "/Users/wang/Documents/VSCode/pythonTest/chapter3/chapter3.py", line 194, in render draw2d(*polygons, axes=False, origin=False, grid=None) File "/Users/wang/Documents/VSCode/pythonTest/chapter3/draw2d.py", line 107, in draw2d poly = Polygon(object.vertices, True) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 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)
