Python (was: Merging core-updates?)

[Andreas Enge]

Hello,

I am having problems with at least two python packages in core-updates:

for python-attrdict.

Both are at their latest version from Pypi.

Have there been some incompatible changes in Python 3.10? Should we revert
the Python update or try to backport patches? (I have no idea about Python,
and probably need it only for calibre.)

PS: On the second issue: The latest commit is this:
    v2.0.1  2019/02/01 -- Haven't used or looked at this in years so updating 
tests to the current version of python and then marking it inactive.
    This would rather make me thing we should drop it, but here we go:
    Building the following 160 packages would ensure 366 dependent packages are 
rebuilt: kicad@6.0.10 ...

    There is something called attrdict3:
    https://pypi.org/project/attrdict3/
    at the same version +0.0.1; maybe we should use this?


PPS: On the first issue, the homepage says:
   PyCrypto 2.x is unmaintained, obsolete, and contains security 
vulnerabilities.
   Please choose one of the following alternatives:
   Cryptography
     Recommended for new applications.
     Newer API with fewer gotchas.
     API docs
     GitHub
     PyPI
   PyCryptodome
     Recommended for existing software that depends on PyCrypto.
     Fork of PyCrypto. Most applications should run unmodified.
     API docs
     GitHub
     PyPI

   Then we have:
      Building the following 6 packages would ensure 9 dependent packages are 
rebuilt: python-miio@0.5.11 ledger-agent@0.9.0 electrum@4.3.2 eolie@0.9.101 
jrnl@1.9.7 poezio@0.13.2
   We already have python-pycryptodome and python-pycryptodomex.
   Maybe we should try rebuilding the 9 dependent packages with one of them?
   Do the specialists have a preference as to which one to use?
   Both have a similar number of dependents currently.
