A file is at EOF when read() returns ''.  The above is the
cleanest, simplest, most direct way to do what you specified.
Everybody does it that way, and everybody recognizes what's
being done.

It's also the "standard, Pythonic" way to do it.

You can do that, but then you're mostly just obfuscating
things.
