Is there any way to upload or utilise a wallet.json file autosaved through cloud mining via python?

Hi all, wonder if you could advise? I build a python mining bot, ran the script and have been able to mine just over 0.02BCT, and it is set up to autosave to a wallet.json file. Here's the thing though, there seems to be no feesible way to upload this file to a wallet, and on my operating system (linux – LMDE 6 – based on Debian 12) it is proving quite bothersome to create a python wallet and use pip.

It just seems that it is quite hard to find any suitable way to extract a private key from this file, and I was wondering if anyone had any suggestions re tbe above?

Many thanks in advance.
