Python 3.14 compatibility issues

[sharkcz]

As found by the Fedora Python maintainers during their preparation for Python 3.14, the changes from PR #146 are not sufficient to resolve the depreciated ast module usage. Please see https://bugzilla.redhat.com/show_bug.cgi?id=2322707 for the full details. The report says

python-simpleeval fails to build with Python 3.14.0a1.

The AttributeError is repeated 100x.:

======================================================================

Thanks for flagging this @sharkcz - I'll try and work on it this week.

@sharkcz -

https://pypi.org/project/simpleeval/1.0.3/

Should fix those warnings now?

[sharkcz]

Thanks, will give it a try and report back.

I have updated the Fedora package to 1.0.3 and it looks good now, please see https://copr.fedorainfracloud.org/coprs/g/python/python3.14/build/8205961/ for details.
