Cannot convert mnemonic to seed

[Erfansol21]

Hi, I'm trying to add a code that import wallet from mnemonic. I tried using the code that was in this issue:
#419
but it couldn't sign a transaction and gave this error: xrpl.asyncio.clients.exceptions.XRPLRequestFailureException: Request failed, invalidTransaction: fails local checks: Invalid signature.
and I tried making a seed from entropy using addresscodec.encode_seed but it gave the wrong seed and address in both ED25519 and SECP256K1

Hello,
Here is a xrpl.js utility function for generating a wallet using a mnemonic phrase: https://js.xrpl.org/classes/Wallet.html#fromMnemonic
We do not have an equivalent utility function in xrpl-py yet.

Here is a script written by @LimpidCrypto for this purpose: #419 (comment) -- I am not familiar with the bip_utils library myself, but this script appears to fit your requirement.
