python-scandir

scandir() is a directory iteration function like os.listdir(),
except that instead of returning a list of bare filenames, it yields
DirEntry objects that include file type and stat information along
with the name. Using scandir() increases the speed of os.walk()
by 2-20 times (depending on the platform and file system) by avoiding
unnecessary calls to os.stat() in most cases.
scandir has been included in the Python 3.5 standard library as
os.scandir(), and the related performance improvements to
os.walk() have also been included. So if you're lucky enough to be
using Python 3.5 (release date September 13, 2015) you get the benefit
immediately, otherwise just
download this module from PyPI <https://pypi.python.org/pypi/scandir>_,
install it with pip install scandir, and then do something like
this in your code::
try:
    from os import scandir, walk
except ImportError:
    from scandir import scandir, walk


PEP 471 <https://www.python.org/dev/peps/pep-0471/>, which is the
PEP that proposes including scandir in the Python standard library,
was accepted <https://mail.python.org/pipermail/python-dev/2014-July/135561.html>
in July 2014 by Victor Stinner, the BDFL-delegate for the PEP.
This scandir module is intended to work on Python 2.6+ and Python
3.2+ (and it has been tested on those versions).
