bip39-slip39 implements the mnemonic schemes of bitcoin wallets, BIP39, SLIP-0039 and Electrum’s, from the entropy to the seed, in typed Python.
It imports nothing but the standard library. What a seed derives to is not here: btclib-wallet is the library above this one.
The package on PyPI is named btclib-mnemonics.
python -m pip install --upgrade btclib-mnemonics
