I am new to python and bitcoin so please bear with my question. I want to integrate bitcoin as a payment method in my platform, I want to use 3rd party api service for sending transactions to block-chain, however as a security measure I want the address generation to be done on my local machine as well as transaction signing, so that the private keys never leave my system.

I have already integrated ethereum by using web3py library. Is there any library available for bitcoin for Python above the same line?
