Python code to find looping subset within a tuple

loopFinder.py

##Finds looping subsets within a progression of chords, listed as a tuple (lick); outputs loop (as tuple) and # of repetitions within lick
def findLoops(lick):
  lickLen = len(lick)
  for i in range(1, lickLen - 1):
    testLoop = lick[0:i] #find loop to test as subset
    loopLen = len(lick[0:i]) #find test loop length
    testVal = int(lickLen/loopLen) #find divisor, rounded down 
    testValRem= lickLen%loopLen #find remainder
			if lick == (testLoop * testVal) + testLoop[0:testValRem]: # if lick = a multiple of the loop (including remainder), then loop is valid loop 
				loop = lick[0:i]
				repeats = lickLen/float(loopLen)
				break
			else:
				loop = lick
				repeats = 1
		return loop, repeats
