Generate HMAC-SHA1 Signature using Python 3

hmac_sha1.py

import hashlib
import hmac
import base64


def make_digest(message, key):
    
    key = bytes(key, 'UTF-8')
    message = bytes(message, 'UTF-8')
    
    digester = hmac.new(key, message, hashlib.sha1)
    #signature1 = digester.hexdigest()
    signature1 = digester.digest()
    #print(signature1)
    
    #signature2 = base64.urlsafe_b64encode(bytes(signature1, 'UTF-8'))
    signature2 = base64.urlsafe_b64encode(signature1)    
    #print(signature2)
    
    return str(signature2, 'UTF-8')
  
    
result = make_digest('message', 'private-key')
print(result)

thanks helpfull man made my day !!!
