Почему вывод строки ошибки (client_secret_file, api_name, api_version, scopes, sep = '-')?

Question

Я копирую код Google.py из https://learndataanalysis.org/export-pandas-dataframe-to-google-sheets-in-python/ для использования create_service. Я не знаю, как ошибка

import datetime
import pickle
import os
from google_auth_oauthlib.flow import Flow, InstalledAppFlow
from googleapiclient.discovery import build
from google.auth.transport.requests import Request


def Create_Service(client_secret_file, api_name, api_version, *scopes):
print(client_secret_file, api_name, api_version, scopes, sep='-')
CLIENT_SECRET_FILE = client_secret_file
API_SERVICE_NAME = api_name
API_VERSION = api_version
SCOPES = [scope for scope in scopes[0]]
print(SCOPES)

cred = None

pickle_file = f'token_{API_SERVICE_NAME}_{API_VERSION}.pickle'
# print(pickle_file)

if os.path.exists(pickle_file):
    with open(pickle_file, 'rb') as token:
        cred = pickle.load(token)

if not cred or not cred.valid:
    if cred and cred.expired and cred.refresh_token:
        cred.refresh(Request())
    else:
        flow = InstalledAppFlow.from_client_secrets_file(
            CLIENT_SECRET_FILE, SCOPES)
        cred = flow.run_local_server()

    with open(pickle_file, 'wb') as token:
        pickle.dump(cred, token)

try:
    service = build(API_SERVICE_NAME, API_VERSION, credentials=cred)
    print(API_SERVICE_NAME, 'service created successfully')
    return service
except Exception as e:
    print(e)
return None

def convert_to_RFC_datetime(year=1900, month=1, day=1, hour=0, minute=0):
  dt = datetime.datetime(year, month, day, hour, minute, 0).isoformat() + 'Z'
return dt

Она вызывает меня так:

File "Google.py", line 10 print(client_secret_file, api_name, api_version, scopes, sep='-') ^ SyntaxError: invalid syntax

Если я удалю эту строку, будет ошибка в pickle_file = f'token_{API_SERVICE_NAME}_{API_VERSION}.pickle'
