我写了一个Python脚本与管理目录和谷歌日历API的。目标是从谷歌工作区域的所有资源日历的重复事件列表，然后修改事件重复结束后90天。我有脚本工作拉所有资源日历的电子邮件地址，将它们添加到一个列表中，然后从所有7个资源日历中提取事件。我似乎找不到一种方法来过滤和获取重复发生的事件，我的脚本获取单个事件和重复事件。我尝试使用event['recurringEventId']，但它出错了。是否有方法将结果从事件过滤为仅重复？
代码如下：

`import datetime
import os.path

from google.auth.transport.requests import Request
from google.oauth2.credentials import Credentials
from google_auth_oauthlib.flow import InstalledAppFlow
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError

#API scopes If modifying these scopes, delete the file token.json.
SCOPES = ['https://www.googleapis.com/auth/calendar.readonly', 
          'https://www.googleapis.com/auth/calendar.events', 
          'https://www.googleapis.com/auth/admin.directory.resource.calendar']

#Create empty list to hold resource calendar emails
cal_list = []
event_list = []

#Authorise app to access Google account
creds = None
# The file token.json stores the user's access and refresh tokens, and is
# created automatically when the authorization flow completes for the first
# time.
if os.path.exists('token.json'):
    creds = Credentials.from_authorized_user_file('token.json', SCOPES)
# If there are no (valid) credentials available, let the user log in.
if not creds or not creds.valid:
    if creds and creds.expired and creds.refresh_token:
        creds.refresh(Request())
    else:
        flow = InstalledAppFlow.from_client_secrets_file(
            'credentials.json', SCOPES)
        creds = flow.run_local_server(port=0)
    # Save the credentials for the next run
    with open('token.json', 'w') as token:
        token.write(creds.to_json())
        

"""Call directory api to list resource calendar email addresses
and add them to cal_list"""
with build('admin', 'directory_v1', credentials=creds) as service_admin:
    calendars = service_admin.resources().calendars().list(customer='C03r7ld3j', maxResults=40).execute()
    for calendar in calendars['items']:
        cal_list.append(calendar['resourceEmail'])
    print(cal_list)
      

service_cal = build('calendar', 'v3', credentials=creds)
#call the calendar api to pull the events from the resource calendar list
page_token = None
for el in cal_list:
    events = service_cal.events().list(calendarId=el, pageToken=page_token).execute()
    for event in events['items']:
        print(event)
    page_token = events.get('nextPageToken')`
