I both the 'nlargest' and the 'sorted' methods.. I could only get the 
sorted to work.. however it would only return values like (3,  edam) 
not the list of words..

Here is what I have now.. Am I over-analyzing this?  It doesn't seem 
like it should be this hard to get the program to print the largest set 
of anagrams first...


def anafind():
	fin = open('text.txt')
	mapdic = {}
	finalres = []			# top answers go here
	for line in fin:
		line = line.strip()
		alphaword = ''.join(sorted(line))	#sorted word as key
		if alphaword not in mapdic:
			mapdic[alphaword] = [line]
		else:
			mapdic[alphaword].append(line)
	topans = sorted((len(mapdic[key]), key) for key in mapdic.keys())[-3:] 
  #top 3 answers
	for key, value in topans: 	#
		finalres.append(mapdic[value])
	print finalres
