Licensing and attribution

Within https://github.com/CryptocurrencyExplorer/CryptocurrencyExplorer/blob/main/Explorer/helpers.py in the classes JSONRPC and JSONRPCException, I've created derivative works of python-bitcoinrpc.
I'd like to know what the best way to attribute python-bitcoinrpc would be here, seeing as I'm not a lawyer.

Thank you :-)
