使用find方法查询其中一条记录时，无法打印

from mongo_db import client

try:
    teachers=client.school.teacher.find()
    for one in teachers:
        print(one["_id"],one["name"])
    print("-----------------------------------")
    teacher=client.school.teacher.find({"name":"陈璐"})
    print(teacher["_id"],teacher["name"])
except Exception as e:
    print(e)

改成  teacher=client.school.teacher.find_one({"name":"陈璐"})

打印没有问题
