python for循环数据存不了mongo库

Question

#问题:想把一批大概500个代理ip存进mongo里，用for循环，但最终只能存进一个二个，请同仁们帮看下，问题出哪了。
#代理数据
import requests
from my_fake_useragent import UserAgent
from lxml import etree

def get_proxy():
#随机生成'user-agent'
headers = {'User-Agent':UserAgent().random()}
#主url
url = 'https://#@%!.#%&#@~.com/free/inha/'
#生成十个主页面
urls = [f'{url}{i}' for i in range(2,11)]

for i in urls:
    #获取response
    r = requests.get(url=i,headers=headers).content.decode('utf8')
    #数据解译
    html = etree.HTML(r)
    ip = html.xpath('//div[@id="list"]//tbody/tr/td[1]/text()')
    port = html.xpath('//div[@id="list"]//tbody//td[2]/text()')
    #数据重构，返回值
    for i,p in zip(ip,port):
        proxies={'https':f'http://{i}:{p}',
            'port':f'{p}',
            'ip':f'{i}'
        }
        #存存文件
        #with open('poxies.json','a')as f:
            #f.write(json.dumps(proxies))
        #返回数据
        yield proxies

#存储mongo
import pymongo
import json
from ip_proxies import get_proxy

#连接数据库
client = pymongo.MongoClient('mongodb://127.0.0.1:27017')
#创建库
db = client['py-m-g']
#创建集合
proxy = db['proxies']

da =get_proxy() #获取一个ip和port字典。

for i in da:
try:
#创建主键
i['_id'] = i['ip']
proxy.insert_one(i)
#print('it is ok')

except Exception as ex:
    print(ex)
    break

运行结果:
E11000 duplicate key error collection: py-m-g.proxies index: id dup key: { _id: "202.55.5.209" }, full error: {'index': 0, 'code': 11000, 'keyPattern': {'_id': 1}, 'keyValue': {'_id': '202.55.5.209'}, 'errmsg': 'E11000 duplicate key error collection: py-m-g.proxies index: id dup key: { _id: "202.55.5.209" }'}
但数据库中也确实存了二三个数据，若存成json文件，一点问题都没有。
