I ask myself that question every time I need to do it. Out of sheer
momentum now, I almost always use
if sys.platform in ('win32',):
I dislike using os.name == 'nt', mostly because if we asked all
Windows Python users which OS they use, only a tiny percentage would
answer "NT". Since NT is a dying OS, 'nt' is an increasingly
odd-looking thing to test agaist.
OTOH, I have no idea when or why sys.platform == "win32" would give a
different result than os.name == "nt".

Like whether to use time.time or time.clock.

My way <wink> -- unless it's broken in some way I haven't bumped into yet.
