python - Is adding folders to system path for reaching other modules is a dirty hack? -


i have commands.py module in directory contain subdirectory script. don't want copy in every folder, contain scripts. bad practice?

import sys sys.path.append("..")  # add previous folder run script sys.path.append(".")  # add current folder if run script in folder, contain commands.py commands import *

sorry bad english.

current folder first entry in sys.path (from python's path-making perspective '' == '.') adding pointless in second case.

the first case more problematic - first of all, current path should first entry if insist on adding folders sys.path @ least insert them @ index 1+, or better, append path end of sys.path ensure built-in , current-folder visible modules accessible intended locations.

finally, due fact different parts using sys.path search path in different ways, setting relative paths not idea. if want hardcode parent path, use os.path.realpath("..").

this under assumption there no other way - i'd still urge rethink design , avoid messing search path entirely.
