Oh, don't do that.  Please?  Just out of respect for anyone who has to
maintain your code.

Functions are easy to define in python, and you don't have to do it
all in one line.  I'd recommend:

def make_name(x):
  suffix = ""
  if x[1] in ("big", "little", "whatever"):
    suffix = x[1]
  name = "%s_%s_%s.txt" % (x[2], x[0], suffix)
  return name
filenames = map(make_name, items)

And, yes, you can just plug this inside any function.

It's longer, but it's both more extensible and easier to read.
