hi in c++ and opengl

has a code that let me draws a grid like this.

void DrawGround(void)
{
GLfloat fExtent = 20.0f;
GLfloat fStep = 1.0f;
GLfloat y = -0.4f;
GLint iLine;

glBegin(GL_LINES);
 for(iLine = -fExtent; iLine <= fExtent; iLine += fStep)
     {
        glVertex3f(iLine, y, fExtent);
        glVertex3f(iLine, y, -fExtent);

        glVertex3f(fExtent, y, iLine);
        glVertex3f(-fExtent, y, iLine);

     }
glEnd();

}

i want convert to python the only what i left is the for loop
i don’t understand how it works for python
