[Tutor] Detecting different list elements and counting them

[Zak Arntson]

Hey! And this solves the "count number of matching items in two lists"
nicely:

###
def count(alist, blist):
	clist = alist + blist
	adict = {}
	for key in clist:
                if key not in adict: adict[key] = 0
		else: adict[key] += 1
	return reduce(lambda x, y: x + y, adict.values())
