Pymongo在子集合中找到？

from pymongo import MongoClient

# 连接MongoDB数据库
client = MongoClient('mongodb://localhost:27017/')

# 选择数据库和集合
db = client['mydatabase']
collection = db['mycollection']

# 查询子集合中的数据
result = collection.find({'subcollection.field': 'value'})

# 遍历查询结果
for document in result:
    print(document)
