teste = 1
while 1:
    input = raw_input("") # or perhaps some form of sys.stdin.read()
    if not input: break

    n = int(input)
    if n != -1:
        break
    
    print "Teste %d\n%d\n\n" % (teste, ((1<<n)+1)*((1 <<n)+1)))
    teste += 1 # or teste = teste + 1 under python 1.5.2
# end while

All of this is untested but the ideas here should point you in the right 
direction.
