Quickly add all dirs to sys.path if dir has .py file (Python)

2012-04-06T16:06:17-07:00

Python recipe 578097 by Andrew Yurisich (add, os_walk, sys_path). Revision 2.

Add all dirs under folder to sys.path if any .py files are found. Use an abspath if you'd rather do it that way.

Uses the current working directory as the location of using.py. Keep in mind that os.walk goes all the way down the directory tree.

Create a nested dictionary from os.walk (Python)

2011-09-26T23:38:24-07:00

Python recipe 577879 by Andrew Clark (dictionary, os_walk). Revision 2.

Creates a nested dictionary that represents a folder structure. Here is an example of what the resulting dictionary might look like:

{
    "root": {
        "folder2": {
            "item2": None, 
            "item1": None
        }, 
        "folder1": {
            "subfolder1": {
                "item2": None, 
                "item1": None
            }, 
            "subfolder2": {
                "item3": None
            }
        }
    }
}

Simultaneous topdown and bottomup variant of os.walk() (alt. title: "Delete .pyc files and empty directories recursively") (Python)

2010-04-21T20:16:09-07:00

Python recipe 577206 by George Sakkis (os_walk).

The standard lib os.walk() function provides a topdown parameter that determines whether entries are yielded in a top-down or a bottom-up order. Sometimes though you may want each directory yielded twice; once before any of its children directories (and recursively their descendants) are yielded and once after they are all yielded. The walk2() function below does this by yielding 4-tuples; the first 3 elements are the same yielded by os.walk() and the 4th is True the first time (topdown) and False the second (bottomup).

An example is deleting all .pyc files and empty directories under some root dir, but excluding specific directories (e.g. VCS specific dirs). The exclusion check should be done topdown (we don't want to descend into any directory that must be excluded) but the check for empty directories has to be done bottom up, since a directory containing only .pyc files will be non-empty initially but empty after removing the files.

Modified os.walk which return current directory depth (Python)

2009-11-06T16:16:42-08:00

Python recipe 576933 by Denis Barmenkov (directory_depth, os_walk, relative_path). Revision 2.

On some task I need to collect file names under specified directory with distance from it. Standard os.walk function do not return depth value.

One solution -- find function which will calculate relative distance from top directory to file.

Another [presented] solution -- modify os.walk so it returns depth level as fourth tuple's value.

Tripwire policy file creator (Python)

2009-02-25T20:30:15-08:00

Python recipe 576670 by Bill Sharer (os_walk, re, text, tripwire).

gen_twpol.py is a script that can be used to generate a tripwire policy source (twpol.txt) for your system.

This script may be distributed under the terms of the Gnu Public License GPLv2 or later.

For more information on the open source version of tripwire see http://sourceforge.net/projects/tripwire/

The tripwire source package usually ships with a an example twpol.txt file based on a RedHat Enterprise (RHEL) distribution, typically an RHEL4 or RHEL5 version. It doesn't do much good to have this get parked by your Gentoo ebuild (nor other distro packager) as all sorts of stuff in /boot, /lib/modules and other places will be out of sync, differently named or just plain missing. In addition, your system may have extra stuff that isn't present in the file but critical to the distro.
