[ANNOUNCE] Twisted 10.2.0 Released

Twisted 10.2.0, the third Twisted release of 2010, has emerged from the mysterious depths of Twisted Matrix Labs, as so many releases before it. Survivors of the release process - what few there were of them - have been heard to claim that this version is "awesome", "even more robust", "fun-siz

Python 3 encoding question: Read a filename from stdin, subsequently open that filename

I've got a couple of programs that read filenames from stdin, and then open those files and do things with them. These programs sort of do the *ix xargs thing, without requiring xargs. In Python 2, these work well. Irrespective of how filenames are encoded, things are opened OK, because it's all
