如何使用python在firestore中批量删除文档

import firebase_admin
from firebase_admin import credentials
from firebase_admin import firestore

cred = credentials.Certificate('path/to/serviceAccountKey.json')
firebase_admin.initialize_app(cred)

db = firestore.client()

batch = db.batch()

# 要删除的文档ID列表
doc_ids = ['doc1', 'doc2', 'doc3']

for doc_id in doc_ids:
    doc_ref = db.collection('collection_name').document(doc_id)
    batch.delete(doc_ref)

# 执行批量删除操作
batch.commit()
