Place this at the top of the script:
import collections
try:
collectionsAbc = collections.abc
except AttributeError:
collectionsAbc = collections
Then change all prefixes of the abstract base types, e.g. change collections.abc.MutableMapping
or collections.MutableMapping
to collectionsAbc.MutableMapping
.
Alternatively, import what you require in the script at the top in a single place:
try:
from collections.abc import Callable # noqa
except ImportError:
from collections import Callable # noqa
