Answer 1

Windows:

>>> import subprocess
>>> subprocess.Popen( "explorer i:" )
<subprocess.Popen object at 0x00C46DB0>

Answer 2

from subprocess import call
targetDirectory = "~/Desktop"
call(["open", targetDirectory])

Answer 3

For Finder the shell command

open ~/

would open a new window.

Answer 4

For OS X, you can use the Finder's Apple Events (AppleScript) interface via py-appscript:

>>> from appscript import *
>>> file_to_show = "/Applications/iTunes.app"
>>> app("Finder").reveal(mactypes.Alias(file_to_show).alias)
app(u'/System/Library/CoreServices/Finder.app').startup_disk.folders[u'Applications'].application_files[u'iTunes.app']
>>> #  Finder window of "Applications" folder appears with iTunes selected

EDIT:

An even simpler solution on OS X 10.6 is to use the new -R (Reveal) option to the open command (see man 1 open):

>>> import subprocess
>>> file_to_show = "/Applications/iTunes.app"
>>> subprocess.call(["open", "-R", file_to_show])
