"Directory this source file is in (and a sibling)"

I have a module which needs to know what directory it's in, and to
refer to files in a sibling directory, something like App/src/foo.py
wants to read App/data/conf.xml . But I have no idea in what context
foo.py is going to be run -- it could be being run as a script, it
could be being imported as a module by another script from anywhere in
the directory structure, it's even possible someone will have called
execfile on it. The following works for everything I've tried:

thisdir = os.path.dirname (os.path.normpa th(__file__))
siblingdir = os.path.normpat h(os.path.join( testdir, os.path.pardir, "sibling"))

However, a colleague expressed disgust at this code, but not really
being a Python programmer had no better suggestions. Is there a neater
way of getting what I want?

If you plan to have your code executed out of a zip or an egg, you may
have problems because __file__ is not what you want, at least with eggs
and Python 2.[34]. There was a brief thread on this topic on the
distutils SIG mailing list within the last few days.

I'm sorry but I can't figure out how to explain this any better than this. In PHP we have a command "require()" that obtains a file and logically places it into another file. I cannot figure out how to do this in bash script as the requirement is necessary for a migration script to obtain the code from a .cfg file and then be able for the "parent" script to run the code it "imported" from the .cfg file, much like PHP's require() or...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...

These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own.... Now, this would greatly impact the work of software developers.
