I am signing a message using TronLink/TronWeb.js but unable to verify it in Python

Python Library I am using https://github.com/iexbase/tron-api-python/

Javascript Code for Signing Message:

const original_message = "557e3517549cf8ed47d8b205654ea2a7"
const signedtxn = await tronWeb.trx.sign(original_message);
// result 0x862e16c28684bed7162e9a1dd34962882d887610de6c775054ffbad989baec65707b2ba898366c02e9f20730bc2daf54bb7e6d33d77c64f8930f8c9365f5993a1b

Python Code for Verifying Signed Message

from tronapi import Tron
from hexbytes import HexBytes

tron = Tron()

class signed_message:
     # signedtxn variable in javascript
    signature = HexBytes('0x862e16c28684bed7162e9a1dd34962882d887610de6c775054ffbad989baec65707b2ba898366c02e9f20730bc2daf54bb7e6d33d77c64f8930f8c9365f5993a1b')

original_message = "557e3517549cf8ed47d8b205654ea2a7"
address = "<!-- Tron Base58 Address in TronLink/TronWeb -->"
tron.trx.verify_message(original_message, signed_message, address=address)

I am getting this error in python

ValueError: Signature does not match

I can verify the message in TronWeb.js but can't in Python

You can use tronpy (yes, I am the author of tronpy.)

PublicKey.verify_msg

the last byte of your signature should be 0x01 or 0x00, which is different from ETH.
