I programmed a few small things with python bitcoinlib. It is truly mindblowing how easy to use it is.

Just Wallet.create('wallet-for-customer-xyz') and you created a wallet. Just w.balance()and it spits out the balance or w.name for the 24 words that one could store in a sql database for each customer.

Python bitcoinlib is truly amazing. It really feels like standing on the shoulders of giants - so much power with so few lines of code.
