Not just PEP8-compliant. Some of these are just plain bad.
The first one I was greeted with when I opened the site was:
> print eval('+'.join(map(str, [1, 1])))
If I ever saw this in production code, I would lose my mind.
It's the kind of one-liner I'd expect to find in an obfuscated code competition. It's not intuitively understood, shows a lack of basic Python functionality (the builtin sum() function), and most of all, it's SLOW. As in, 54 times slower than a simple sum -- tested on xrange(1,10) -- on my development Macbook Pro.
That said, clicking through some other examples, there are a lot of great Python examples on this site. Just beware of some of them, and always make sure you test new code yourself.
