import bpy

start_position = [-31, 138, 2.7]
positions = [ [0,3,2], [4, 1, 6], [3, -5, 1], [3, 10, 1], [1, 8, 1]]

    ob = bpy.data.objects[name]
    bpy.context.scene.frame_set(frame_num)
    ob.location = xyz
    ob.keyframe_insert(data_path="location", index = -1)


frame_num = 0;
for position in positions:
    cal_position = [position[0] + start_position[0], position[1] + start_position[1], position[2] + start_position[2]]
    set_object_a_keyframe_for_location("BENKO", cal_position, frame_num)
    frame_num += 50
