os.access(path, mode) does just this, check it out.
Cross-platform-ness isn't a problem, the docs say it is available for
Windows, Unix and Mac, and I've used it without a hitch on Win2k, WinXP
and various Linux and Unix platforms.
>>> help(os.access)
Help on built-in function access in module nt:
access(...)
access(path, mode) -> 1 if granted, 0 otherwise
Use the real uid/gid to test for access to a path. Note that most
operations will use the effective uid/gid, therefore this routine
can
be used in a suid/sgid environment to test if the invoking user has
the
specified access to the path. The mode argument can be F_OK to
test
existence, or the inclusive-OR of R_OK, W_OK, and X_OK.
