I have a directory that stores all the .py files.
bin/
main.py
user.py # where class User resides
dir.py # where class Dir resides
You can import the module and have access through its name if you don't want to mix functions and classes with yours
import util # imports util.py
util.clean()
util.setup(4)
or you can import the functions and classes to your code
from util import clean, setup
clean()
setup(4)
you can use wildchar * to import everything in that module to your code
from util import *
clean()
setup(4)
