在 Python 中將 BIP-39 助記符轉換為乙太坊私鑰

如何在 Python 中將 BIP-39 助記符轉換為乙太坊私鑰（通過 BIP-44 密鑰派生）？我發現給我預期結果的所有庫都取決於two1包，它與現代版本的requests.

我找到了https://github.com/vergl4s/ethereum-mnemonic-utils/ ，它產生了一個私鑰，但它不正確（或者至少它與https://iancoleman.io/bip39/派生的內容不匹配和truffle-hdwallet-provider節點包）。

我意識到我的錯誤：https ://github.com/vergl4s/ethereum-mnemonic-utils有效，但我正在尋找的完整派生路徑是m/44'/60'/0'/0/0（注意額外/0選擇第一個帳戶）。這是一個完整的例子：
