Is there a Python module to "thaw" data frozen using Perl's Storable?
It's not immediately clear to me how far along this project is, but it appears to aim to do what you want:
https://pypi.org/project/storable/
If your first option doesn't work, another option would be to write a simple perl script to thaw the data, and then write it out in JSON or YAML or some format that you can easily work with in Python.
