Selecting every second keyframe

Hi, is there a way to select every second or nth frame?
I have ~hundred frames - baked range, and to create shivering effect I need to select each second key-frame.
Doing it manually would take ~10 minutes every time.

Run this code in a Python tab. The "2" popping up throughout the code just means that while looping through the list, it will act on every other item, essentially its your "nth item" value. Let me know if there are any issues.

Code:
import maya.cmds as mc

object = mc.ls(selection =True)[0]
keys = mc.keyframe(object, query =True)

i = 0
while i < len(keys):
	mc.selectKey(object, k =True, time = (keys[i], keys[i]), add =True)
	i = i+2
print "Selected " + str(len(keys[::2])) + " keys: ", str(keys[::2])
