longest sequence

[Mark McEahern]

How do you detetermine the longest sequence?  Naive use of max doesn't work
(for this):

  >>> max('1111', '222')
  '222'

so I came up with this:

  def longest(*args):
      sorted = list(args)
      sorted.sort(lambda x, y: cmp(len(x), len(y)))
      return sorted[-1]

Comments?
