SharePoint :如何在事务中执行一系列操作？

from office365.runtime.auth.authentication_context import AuthenticationContext
from office365.sharepoint.client_context import ClientContext

# 设置SharePoint站点URL和用户凭据
site_url = 'https://your-domain.sharepoint.com/sites/your-site'
username = 'your-username'
password = 'your-password'

# 创建一个身份验证上下文
context_auth = AuthenticationContext(url=site_url)

# 使用用户凭据进行身份验证
if context_auth.acquire_token_for_user(username, password):
    # 创建一个客户端上下文
    ctx = ClientContext(site_url, context_auth)

    # 在事务中执行一系列操作
    with ctx.transaction_begin():
        # 在这里执行你的操作
        pass

    # 提交事务
    ctx.transaction_commit()
else:
    print('Error: Unable to authenticate user.')
