I recently wrote a program to do some record-keeping for me. I found
myself hard-coding a bunch of different values into it. This didn't
seem right, so I made my first use of configparser.ConfigParser().
Created the configuration file and everything is working fine.
However, I wrote it based on the assumption that the program is
running in the directory where the config file is stored, and has
a specific name. I started having some second thoughts here.
I thought about putting the location of the configuration file in
the configuration file, but that seemed like a non-starter.[1]
Should I specify the location of the config file with a command-line
option, or is requiring the program to be executed in the directory
containing the configuration file considered acceptable practice?
Eh, there are so many context-dependent practices that it's largely
impossible to identify something to call a "best practice" these days.
I'm going to make a couple of comments, but there's more to consider
than just these thoughts.
There's a sort-of-standard package called platformdirs (a successor to
appdirs) which tries to tell you where to put things in a
platform-independent way.
https://pypi.org/project/platformdirs/
https://pypi.org/project/appdirs/
This works nicely if you're building something to distribute, and you
want to have a system-neutral way to access a config file. For personal
stuff, that may be overkill. If it's only for you, just do what works.
Enhancement: have a default location for the config file hard-coded, but
provide a cmdline option to give an alternative.
