Help on module ntpath:
NAME
ntpath - Common pathname manipulations, WindowsNT/95 version.
FILE
c:\data\utils\python24\lib\ntpath.py
DESCRIPTION
Instead of importing this module directly, import os and refer to
this
module as os.path.
FUNCTIONS
abspath(path)
Return the absolute version of a path
basename(p)
Returns the final component of a pathname
commonprefix(m)
Given a list of pathnames, returns the longest common leading
component
dirname(p)
Returns the directory component of a pathname
exists(path)
Test whether a path exists
expanduser(path)
Expand ~ and ~user constructs.
If user or $HOME is unknown, do nothing.
expandvars(path)
Expand shell variables of form $var and ${var}.
Unknown variables are left unchanged.
getatime(filename)
Return the last access time of a file, reported by os.stat()
getctime(filename)
Return the creation time of a file, reported by os.stat().
getmtime(filename)
Return the last modification time of a file, reported by
os.stat()
getsize(filename)
Return the size of a file, reported by os.stat()
isabs(s)
Test whether a path is absolute
isdir(path)
Test whether a path is a directory
isfile(path)
Test whether a path is a regular file
islink(path)
Test for symbolic link. On WindowsNT/95 always returns false
ismount(path)
Test whether a path is a mount point (defined as root of drive)
join(a, *p)
Join two or more pathname components, inserting "\" as needed
normcase(s)
Normalize case of pathname.
Makes all characters lowercase and all slashes into
backslashes.
normpath(path)
Normalize path, eliminating double slashes, etc.
realpath = abspath(path)
Return the absolute version of a path
split(p)
Split a pathname.
Return tuple (head, tail) where tail is everything after the
final slash.
Either part may be empty.
splitdrive(p)
Split a pathname into drive and path specifiers. Returns a
2-tuple
"(drive,path)"; either part may be empty
splitext(p)
Split the extension from a pathname.
Extension is everything from the last dot to the end.
Return (root, ext), either part may be empty.
splitunc(p)
Split a pathname into UNC mount point and relative path
specifiers.
Return a 2-tuple (unc, rest); either part may be empty.
If unc is not empty, it has the form '//host/mount' (or similar
using backslashes). unc+rest is always the input path.
Paths containing drive letters never have an UNC part.
walk(top, func, arg)
Directory tree walk with callback function.
For each directory in the directory tree rooted at top
(including top
itself, but excluding '.' and '..'), call func(arg, dirname,
fnames).
dirname is the name of the directory, and fnames a list of the
names of
the files and subdirectories in dirname (excluding '.' and
'..'). func
may modify the fnames list in-place (e.g. via del or slice
assignment),
and walk will only recurse into the subdirectories whose names
remain in
fnames; this can be used to implement a filter, or to impose a
specific
order of visiting. No semantics are defined for, or required
of, arg,
beyond that arg is always passed to func. It can be used,
e.g., to pass
a filename pattern, or a mutable object designed to accumulate
statistics. Passing None for arg is common.
