I thought it would be accessible via the win32net functions,
but it seems not. According to this page:

http://www.microsoft.com/technet/scriptcenter/resources/qanda/jun05/hey0603.mspx

it's possible, but not slick. If you wanted to follow their
line and use WMI to access the registry, you could additionally
use the WMI Win32_UserAccount class to work out the SID you need.
For example, to find my profile on this machine, the following
seems to work:

(uses the wmi module from http://timgolden.me.uk/python/wmi.html)

<code>
import _winreg
import win32api
import wmi

#
# Use the current username in DOM\USER format
#
USERNAME = win32api.GetUserNameEx (2)
## USERNAME = "GOYLE\\tim"

HKLM = 0x80000002
profiles_key = r"SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList"

c = wmi.WMI (find_classes=False)
for account in c.Win32_UserAccount (Caption=USERNAME):
   sid = account.SID
   break
else:
   raise Exception, "User %s not found" % USERNAME

registry = wmi.WMI (find_classes=False, namespace="default").StdRegProv
result, profile = registry.GetExpandedStringValue (
   _winreg.HKEY_LOCAL_MACHINE,
   profiles_key + "\\" + sid,
   "ProfileImagePath"
)

print USERNAME, "has profile at", profile
</code>
