type for sequences

[Skaperen]

is there a common parent type for all sequence types that would make it simpler to test if some object is any sequence using isinstance() without having to construct a big list that varies between python2 and python3?

Well, I learned something just now:

import collections for x in (list(), dict(), tuple(), set()): print(isinstance(x, (collections.abc.Mapping, collections.abc.Set, collections.abc.Sequence)))

python 3 for stullis:

>>> from collections import abc >>> for x in (list(), dict(), tuple(), set()): ... print(isinstance(x, (abc.Mapping, abc.Set, abc.Sequence))

Disregard,
Misread code

from collections import abc all(isinstance(x, (abc.Mapping, abc.Set, abc.Sequence)) for x in (list(), dict(), tuple(), set(), str(), bytes(), bytearray(), frozenset()))
