Create standard 65-byte EDCSA signature

[ServantMaximus]

I am trying to use the following api: https://docs.opensea.io/v2.0/reference/create-an-offer

One of the mandatory fields is: "signature"

According to the manual this should be a standard 65-byte EDCSA (or 64-byte EIP-2098, or an EIP-1271)

How can I create this 65-byte EDCSA from my wallet using preferable python?
Please point me to the right way if possible.

You can use EIP-712 along with the type hashes derived here. If you are using web3.py it has eip-712 support.
