Importing the Iterable, Sequence, and Mapping ABCs directly from collections was deprecated in Python 3.3 and the aliases were removed in Python 3.10. Attempt to import from the new location, but if it fails because the current Python is older than 3.3, fall back to the old location.

Thanks! Yes, back in the day it was the intent. I don't know how valid it is nowadays, but let's keep it as you propose. |

Importing the
Iterable,Sequence, andMappingABCs directly fromcollectionswas deprecated in Python 3.3 and the aliases were removed in Python 3.10.Based on other indications in this repository, I believe that the intent is still to support Python 2.7, so this PR attempts to import from the new location, but if it fails because the current Python is older than 3.3, falls back to the old location. If that's not the intent, I can remove these fallbacks.
