Python3.5.1 PyopenGL模块调用出错

Question

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：

 ============= RESTART: F:\Python35-32\Code\PyOpenGLCode\Test.py =============
Traceback (most recent call last):
