This is even more fun:

import sys, operator
lines = open(sys.argv[1]).readlines()
def ifthenelse(condition, true, false):
   if condition:
      return true()
   return false()
map(lambda a, b, list=lines: ifthenelse(list.count(a)>1, lambda
b=b,list=list: operator.delitem(list,b), lambda a=a: a), lines,
range(len(lines)))
open(sys.argv[2],'w').writelines(lines)

but it's kind of pointless.
