Python 3: anydbm import is outdated (should use dbm) #1524
Description
While working with the codebase, I noticed references to anydbm.
In Python 2, anydbm was part of the standard library.
In Python 3, anydbm was removed and replaced by dbm.
Right now, this might not cause a direct crash (because the code has a Python 3 fallback), but leaving anydbm references around could confuse contributors and potentially cause issues in future Python versions or environments.
