As an implementation detail, most modules have the name __builtins__ made available as part of their globals. The value of __builtins__ is normally either this module or the value of this module’s __dict__ attribute. Since this is an implementation detail, it may not be used by alternate implementations of Python.
Для чего в def обязательно писать return
return останавливает выполнение текущей подпрограммы (функции), возвращает выполнение к месту её вызова и, опционально, устанавливает возвращаемое значение функции. def subsets(seq):
