I want to remove the x and y locations in fcurve using codes. I can remove all location channels in fcurve using codes, but I don't know which one x or y is. If the fcurve contains x,y,z, I remove the first two. This is fine. What if the fcurve contains only x and z?

OK... I somehow find the solution. Blender can figure out xyz channels by array_index of the location. 0->x,1->y,2->z. If I change 0 to 1, then I will get two Y-location channels...
