Executing Python script but getting BOT Error

Steps on how to execute the below Python script: Do we need to install any libraries on the server? as the below script is providing an output outside of the A360

import datetime
import base64
import hmac
import hashlib
import time
 
 
def hmac_sha256(message, key):
    key = bytes(key, 'UTF-8')
    message = bytes(message, 'UTF-8')
    h = hmac.new(key, message, hashlib.sha256)
    return base64.b64encode(h.digest()).decode()
 
def authorization(strAKID, strAKSecret):
    
    strDateNow = datetime.datetime.utcnow().strftime('%a, %d %b %Y %H:%M:%S GMT')
    print(f"date is: {strDateNow}")
    strSignContent = "date: {}".format(strDateNow)
    #Compute signature, get authorization
    strSignature = hmac_sha256(strSignContent, strAKSecret)
    print(f"signature is: {strSignature}")
    strAuthorization = '''hmac username="{}", algorithm="hmac-sha256", headers="date", signature="{}"'''.format(strAKID, strSignature)
if __name__ == '__main__':

    strAKID = "e2c5b464-5361-40f2-9c8e-bc04962db1a7"
    strAKSecret = "I5lGga3vfFW8Nf9HbRHuUnROcga0SnpP"
    authorization(strAKID, strAKSecret)
