Question

我的python代码不会运行！？

我不知道如何解决这个问题。有人可以帮帮我吗？

错误：

Traceback (most recent call last):
File "C:\Python27\lib\site-packages\OpenGL\GLUT\special.py", line 120, in safeCall

这两行是一个问题：

 point2Array=[]
 numpy = point2Array([[0,3],[0,6],[4,6],[6,4],[6,0],[3,0]])

您已创建list对象并将其绑定到名称point2Array。您随后调用该对象。

您不能() list。

也许你想说：

point2Array = numpy.array([[0,3],[0,6],[4,6],[6,4],[6,0],[3,0]])

或者你的意思是：

point2Array = [[0,3],[0,6],[4,6],[6,4],[6,0],[3,0]]
