Hi, python beginner starting a new project here.
This project will store most of its actual data in a shared-database, but
I have a small amount of user specific data that I need to be stored like
configuration or preferences for example, the list of databases that the
program should connect to.
On Unix this might be a .file, on windows this could be in the registry,
or an ini file or an xml file in ProgramData or AppData or something.
Is there a pythony way to store such config data, perhaps there is
already a standard python package for such a purpose?
My app uses Qt, and Qt has its method of doing it (QSettings), but for
architectural reasons I don't want to use it.
Could sqlite be an option perhaps? I am still undecided if the ability
for the user to edit the file independently of the program is a good or
bad thing.
Thanks a lot.

One way I've just started to use it to create a utility function to
return the location of the user data folder, depending on the operating
system:
import os, sys
def GetUserDataDirectory():
dir = None
# WINDOWS
if os.name == "nt":
# Try env APPDATA or USERPROFILE or HOMEDRIVE/HOMEPATH
if "APPDATA" in os.environ:
dir = os.environ["APPDATA"]
if ((dir is None) or (not os.path.isdir(dir))) and ("USERPROFILE"
in os.environ):
dir = os.environ["USERPROFILE"]
if os.path.isdir(os.path.join(dir, "Application Data")):
dir = os.path.join(dir, "Application Data"))
if ((dir is None) or (not os.path.isdir(dir))) and ("HOMEDRIVE"
in os.environ) and ("HOMEPATH" in os.environ):
dir = os.environ["HOMEDRIVE"] + os.environ["HOMEPATH"]
if os.path.isdir(os.path.join(dir, "Application Data")):
dir = os.path.join(dir, "Application Data"))
if (dir is None) or (not os.path.isdir(dir))
dir = os.path.expanduser("~")
# One windows, add vendor and app name
dir = os.path.join(dir, "vendor", "app")
# Mac
elif os.name == "mac": # ?? may not be entirely correct
dir = os.path.expanduser("~")
dir = os.path.join(dir, "Library", "Application Support")
dir = os.path.join(dir, "vendor", "app")
# Unix/Linux/all others
else:
dir = os.path.expanduser("~")
dir = os.path.join(dir, ".app")
# Some applications include vendor
# dir = os.path.join(dir, ".vendor", "app")
return dir
