Sums to X

Determine the number of unique pairs of values in a given list that sum up to an inputed value. For each qualifying pair, print out the location of the two values.

	def sumsToX(num,listOfValues):
	    sumFoundCnt = 0
	    outer = 0
	    while (outer < len(listOfValues)):
	        inner = outer + 1
	        while (inner < len(listOfValues)):
	            if ((listOfValues[outer]+listOfValues[inner]) == num):
	                sumFoundCnt = sumFoundCnt + 1
	            inner = inner + 1

	        outer = outer + 1

	    if (sumFoundCnt == 0):
	        print "No two values in the list add up to ", num
	    else:
	        print sumFoundCnt, " different pairs of numbers add up to ", num
