I wrote a code to get exchange rate information with python, but it doesn't work. I'm new to coding, so what's the problem?

print(pre_hash_string)
hash_string = hmac.new(secret, pre_hash_string, digestmod=hashlib.sha256).hexdigest()
x_pay_token = 'xv2:' + timestamp + ':' + hash_string
print(x_pay_token)

try:
