Importing

To increase readability, the best practice is to import whole modules. Then, it is clear where the functions come from. In addition, it helps to avoid circular imports.

No:

from os import *
from os import listdir

Yes:

import os
import os.path
from os import path

Only classes are “allowed” to be imported directly as long as there are not name clashes:

from somewhere import ThisClass

Put imports at the top of the module and divide them in 3 sections:

• System

• 3rd party

• Local
