bitcoinlib library should do the job. I've made sure there's option to enter your own BIP39 seed phrase and path. Here's example code (i checked the result with https://iancoleman.io/bip39/),

Code:

>>> from bitcoinlib.wallets import Wallet
>>> mnemonic = "jaguar laptop random problem corn nut fun happy maximum federal wrap address"
>>> w = Wallet.create('Wallet1', keys=mnemonic, network='bitcoin')
>>> k = w.key_for_path([0, 0])
>>> k.address
'17AmSBNzGunnuPzCiJoTV2mdqu4v9Jt7QY'
>>> k = w.key_for_path([0, 1])
>>> k.address
'1Q9UgCADh16mfVaA5xmKxiCLZuiCG1g3zr'

Need to quickly get some Python for deriving private keys at a path given a seed, as I'm trying to create payment addresses for users on my website. (The addresses will be used in my Flask server and stored in a database.)

The seed phrase itself is going to be stored in some libsodium-kind of container, so no need to worry about that.
