scandir: Fast file system iteration for Python¶
scandir, a better directory iterator and faster os.walk()
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.
Equivalent System Packages¶
$ conda install python:scandir
macports: install the following packages: python:scandir opensuse:
$ sudo zypper install python:scandir
However, these system packages will not be used for building Sage because using Python site-packages is not supported by the Sage distribution; see https://trac.sagemath.org/ticket/29023
