PyOpenGL provides coverage of all GLUT API versions and the calling convention for the exposed functions are identical to that of the C binding, with a few minor exceptions.
First, the glutInit function takes a list of arguments (usually sys.argv, but not sys.argv[1:]) and returns all non GLUT arguments. For example
import sys my_argv = glutInit(sys.argv)
Secondly, setting callbacks in Python is done in the same way as done in C, but Python has no NULL pointer so None is used to clear a callback instead, i.e.
def on_display(): pass glutDisplayFunc(on_display) # set the callback glutDisplayFunc(None) # clear the callback
