if you use relative paths for file or directory names python will look for them (or create them) in your current working directory (the $PWD
variable in bash).
if you want to have them relative to the current python file, you can use (python 3.4)
from pathlib import Path
HERE = Path(__file__).parent.resolve()
CONFIG_PATH = HERE / '../etc/mysql_config.ini'
or (python 2.7)
import os.path
HERE = os.path.abspath(os.path.dirname(__file__))
CONFIG_PATH = os.path.join(HERE, '../etc/mysql_config.ini')
if your mysql_config.ini
file lives in the etc
directory below your python script.
you could of course always use absolute paths (starting with a /
; i.e. /home/someuser/mysql_config.ini
).
