测试PyopenGL模块的源代码来自网上：
from OpenGL.GL import *
from OpenGL.GLU import *
from OpenGL.GLUT import *
def drawFunc():
glClear(GL_COLOR_BUFFER_BIT)
#glRotatef(1, 0, 1, 0)
glutWireTeapot(0.5)
glFlush()
glutInit()
glutInitDisplayMode(GLUT_SINGLE | GLUT_RGBA)
glutInitWindowSize(400, 400)
glutCreateWindow("First")
glutDisplayFunc(drawFunc)
#glutIdleFunc(drawFunc)
glutMainLoop()
运行错误提示如下：
