Hi -- thanks for the report! You haven't given us many details here, but I think this is intentional behaviour, not a bug -- this was changed in Issue37324. Importing `Mapping` (along with many other names) directly from `collections`, instead of from `collections.abc`, has been deprecated since Python 3.3, and was removed in Python 3.10. So instead of writing `from collections import Mapping`, simply write `from collections.abc import Mapping`, and you should find that no error is raised. |

Hi mareklachbc,
What makes you think that this is a bug?
Since at least version 3.7, you will have seen this warning:
>>> import collections
>>> collections.Mapping
__main__:1: DeprecationWarning: Using or importing the ABCs from
'collections' instead of from 'collections.abc' is deprecated
since Python 3.3,and in 3.9 it will stop working
So this is not a bug.
