Constructing paths in Python
Rather than hard-coding paths it's better to use path construction operators.
In the past this was done with os.path but a more modern library is pathlib.
import os
import pathlib
from pathlib import Path
I'll show both, side by side.
Get directory of the current script
SCRIPT_DIR = Path(__file__).parent.absolute()
SCRIPT_DIR = os.path.dirname(os.path.abspath(__file))
Get the user home directory
HOME_DIR = Path.home
HOME_DIR = os.environ.get("HOME")
Construct a path from $HOME
HOME_DIR = Path.home
HOME_DIR = os.environ.get("HOME")
SUB_DIR = HOME_DIR / "repos" / "systems-obscure" / "src"
SUB_DIR = os.path.join(HOME_DIR, "repos", "systems-obscure", "src")
Access root directories
It's less straightforward to access directories that are not children of
$HOME.
For instance to access mounted drives:
EXT_HD = Path("/media/samsung-T3")
EXT_HD_DIR = EXT_HD / "music"
EXT_HD = "/media/samsung-T3"
EXT_HD_DIR = os.path.join(EXT_HD, "music")
