Answer 1

You can do this by starting a full node on your computer and connecting to it with python-bitcoinrpc. After the node is fully configured and rpc is up and running you can get a new address on python with AuthServiceProxy(" http://%s:%s@127.0.0.1:8332 "%(RPC_USER, RPC_PASSWORD).getnewaddress() which returns the address as a string.

from Crypto.PublicKey import RSA
import Crypto.Random

 def generate_keys(self):
        # those keys are in binary format.
        # Crypto.Random is the function that generates the random key.
        private_key=RSA.generate(1024, Crypto.Random.new().read)
        public_key=private_key.publickey()
        # DER is a binary format for data structures described by ASN.
        # from hex we decode it to ascii characters
        return binascii.hexlify(private_key.exportKey(format="DER")).decode('ascii'), binascii.hexlify(public_key.exportKey(format="DER")).decode('ascii')

I've found the bitmerchant package to be useful for this.

You can easily create new wallets as well as child wallets along with public and private keys. The examples on the github page are quite easy to follow.
