 If needed you can use your mnemonic phrase (the 12 or 24 words you had to write down when creating your wallet) to generate your private key in python. First install eth_account:

 Some general best practices (non exhaustive):
+
 * Don't ever run this conversion online. Online tools 'facilitating' this conversion are likely scams and will steal your funds.
 * Always keep your mnemonic phrase and private key (basically the same thing) private.
 * Don't use the same mnemonic as the one you had to backup when initializing a hardware wallet, using the same mnemonic basically deletes the security of your hardware wallet.
