Pre1990List = [line.rstrip() for line in infile]
infile.close()
Pre1990Set = set(Pre1990List)
infile = open(“Retired.txt”,’r’)
RetiredList = [line.rstrip() for line in infile]
infile.close()
RetiredSet = set(RetiredList)
Pre1990Set = Pre1990Set.difference(RetiredList)
infile = open(“Added.txt”,’r’)
AddedList = [line.rstrip() for line in infile]
infile.close()
AddedSet = set(AddedList)
Post1990Set = Pre1990Set.union(AddedSet)
Post1990Set = sorted(Post1990Set)
Post1990List = list(Post1990Set)
Post1990String = (‘n’).join(Post1990List)
outfile = open(“Post1990.txt”,’w’)
outfile.write(Post1990String)
outfile.close()
