According to the PyOpenGL manual:

C Specification

void glMap2d ( GLenum target, GLdouble u1, GLdouble u2, GLint ustride, 
GLint uorder,
GLdouble v1, GLdouble v2, GLint vstride, GLint vorder, const GLdouble 
*points);
void glMap2f ( GLenum target, GLfloat u1, GLfloat u2, GLint ustride, 
GLint uorder,
GLfloat v1, GLfloat v2, GLint vstride, GLint vorder, const GLfloat *points);

Python Specification
glMap2d ( target, u1, u2, v1, v2, points[][][]) → None
glMap2f ( target, u1, u2, v1, v2, points[][][]) → None

The C calls take 10 parameters, but the Python versions take far fewer. 
Instead of passing in a pointer and some stride and order information 
describing how it is organized as an array, Python just accepts the array
