a function 'islastline' is missing to fileinput module. when that function exists, it is possible to perform an action at the end of a file like in: for line in fileinput.input(): processline(line) if fileinput.lastline(): processfile() Without this function, the same script looks like: for line in fileinput.input(): if fileinput.isfirstline() and fileinput.lineno() != 1: processfile() processline(line) processfile()

Logged In: YES user_id=80475 Reclassifying as a feature request. I'm -0 on complicating this venerable interface. Also, I find it unnatural for the inside of a loop to be able to ascertain whether it is in its final iteration. The closest approximation is the for-else clause which is vary rarely used in normal python programming. While the OP was able to sketch a use case, it involved only saving a couple of lines over what can be done with the existing API. P.S. There is a less buggy version of the patch at www.python.org/sf/968063
