Calculate hmac value with base64 encode using sha256 python - php

Question

I'm trying to transform a php code into python language.
the php function calculates the hmac value using sha256 and base64 encoding.
My Php function:
<?php
define('SHOPIFY_APP_SECRET', 'some_key');
function verify_webhook($data)
{
$calculated_hmac = base64_encode(hash_hmac('sha256', $data,
SHOPIFY_APP_SECRET, true));
echo $calculated_hmac;
}
$data = "some_data";
$verified = verify_webhook($data);
?>
My Python function:
import base64
import hmac
import binascii
from hashlib import sha256
API_SECRET_KEY = "some_key"
data = "some_data"
def verify_webhook():
dig = hmac.new(
API_SECRET_KEY,
msg=data,
digestmod=sha256
).digest()
calculated_hmac = base64.b64encode(bytes(binascii.hexlify(dig)))
print(calculated_hmac)
verify_webhook()
I got different outputs even I have the same key and data. I still don't know what I'm missing here. please help!
Python output:

Php output:

I was able to match your php output using Python 3:
>>> dig = hmac.new( bytes(API_SECRET_KEY,'ascii'),
msg=bytes(data, 'ascii'), digestmod=sha256 )
>>> dig.digest()
b'7\xb2r\x03"\xa8r\x80\xf1\xfc\xeaq\xdf\xa9\xc6\xa8\x0b\x94)\xdc\x86\x1f\xe4N_\xe2y\x00\x98\x10\xfb\xf8'
>>> base64.b64encode(dig.digest())
