推荐答案

要查找集合，可以使用 collection_names() - http://api.mongodb.org/python/current/api/pymongo/database.html#pymongo.database.Database.collection_names

To find the collections, you can use collection_names() - http://api.mongodb.org/python/current/api/pymongo/database.html#pymongo.database.Database.collection_names

collection_names 从 3.7 开始被弃用，并被替换为 list_collection_names - https://api.mongodb.com/python/current/api/pymongo/database.html#pymongo.database.Database.list_collection_names

The collection_names is deprecated from 3.7 onwards and been replaced by list_collection_names - https://api.mongodb.com/python/current/api/pymongo/database.html#pymongo.database.Database.list_collection_names
