Attempt to call an undefined function glutInit

I need a glut window in python. I have the following exception using Python 3.5 and PyOpenGL.GLUT

Traceback (most recent call last):
  File "D:\...\Test.py", line 47, in <module>

    if __name__ == '__main__': main()
  File "D:\...\Test.py", line 9, in main
    glutInit(sys.argv)
  File "C:\...\OpenGL\GLUT\special.py", line 333, in glutInit
    _base_glutInit( ctypes.byref(count), holder )
  File "C:\...\OpenGL\platform\baseplatform.py", line 407, in __call__
    self.__name__, self.__name__,

OpenGL.error.NullFunctionError: Attempt to call an undefined function glutInit,
check for bool(glutInit) before calling

Platform: Windows

Why do i get this error?

Here is my code:

from OpenGL.GLUT import *
import sys

glutInit(sys.argv)

Problems:

• There was no problem with pip install or easy_install
• The glut.dll and glut32.dll were missing. (They are not part of the PyPI package) you have to install them separately or download it like I did.

Unzipped the dll files from the glutdlls.zip and placed them next to my python file.

Note: You can add the dll files to your PATH variable. Not necessary to keep them next to the py file.
