Вторая по частоте future-функция, которую я использовал, это абсолютный импорт
from __future__ import absolute_import
Что она делает?
Изменения, которые вносит эта инъекция описаны в PEP328
Покажу простой пример.
Допустим, есть такой пакет:
/my_package
/__init__.py
/main.py
/string.py
Смотрим код в my_package/main.py
# main.py
import string
Простой пример готов) Вопрос в том, какой модуль импортируется в данном случае? Есть два варианта:
1. модуль в моём пакете my_package.string
2. стандартный модуль string
И вот тут вступает в дело приоритет импортов. В Python2 порядок следующий: помимо иных источников, раньше ищется модуль внутри текущего пакета, а потом в стандартных библиотеках. Таким образом мы импортнём my_package.string.
Но в Python3 это поведение изменилось. Если мы указываем просто имя пакета, то ищется именно такой модуль, игнорируя имена в текущем пакете. Если мы хотим импортнуть именно подмодуль из нашего пакета то, мы должны теперь явно это указывать.
from my_package import string
или относительный импорт, но с указанием пути относительно текущего модуля main
from . import string
Еще одной неоднозначностью меньше 😎
