After some research, I found a way to play the "peek" and "pop" taptic engine effects. This is tested on my iPhone 6s. See code below. Hope it helps.
from objc_util import *
UIDevice = ObjCClass('UIDevice')
def taptic_peek():
d = UIDevice.new()
t = d._tapticEngine()
t.actuateFeedback_(1001) # or t.actuateFeedback_(0)
def taptic_pop():
d = UIDevice.new()
t = d._tapticEngine()
t.actuateFeedback_(1002) # or t.actuateFeedback_(1)
def taptic_triple_knock():
d = UIDevice.new()
t = d._tapticEngine()
t.actuateFeedback_(2)

Some update:
On my iPhone 6s with iOS 10, actuateFeedback_(0) seems to give the same result as actuateFeedback_(1001), and actuateFeedback_(1) the same as actuateFeedback_(1002).
Also, I found that actuateFeedback_(2) gives the quick triple knock you get when you flip the vibrate/ring switch. Code has been updated above.
