返回信息流按教程的代码如下：

from OpenGL.GL import *
from OpenGL.GLUT import *
from OpenGL.GLU import *
import sys
class OpenGLWindow:
def __init__(self,width=640,height=480,title="PyOpenGL"):
glutInit(sys.argv)
glutInitDisplayMode(GLUT_RGBA|GLUT_DOUBLE|GLUT_DEPTH)
glutInitWindowSize(width,height)
self.window=glutCreateWindow(title)
glutDisplayFunc(self.Draw)
self.InitGL(width,height)
def Draw(self):
glClear(GL_COLOR_BUFFER_BIT|GL_DEPTH_BUFFER_BIT)
glLoadIdentity()
glutSwapBuffers()
def InitGL(self,width,height):

glLoadIdentity()
gluPerspective(45.0,float(width)/float(width),0.1,100.0)
glMatrixMode(GL_MODELVIEW)
def MainLoop(self):
glutMainLoop()
window=OpenGLWindow()
window.MainLoop()
分隔线--------------------------------------------------
然后提示错误：
C:\Python27\python.exe C:/Python27/OpenGL_1.py
Traceback (most recent call last):

self.__name__, self.__name__,
OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit, check for bool(glutInit) before calling
这是为什么呢？glutInit()函数为什么跪了，难道需要自己写？
