重复爬取同页的第一个内容

from lxml import etree
import requests
import csv
f=open(r'C:\Users\86182\Desktop\jinan.csv','wt',newline='',encoding='utf-8')
writer=csv.writer(f)
writer.writerow(('name','price','address'))
urls=['https://jn.newhouse.fang.com/house/asp/trans/buynewhouse/default.htm?page={}&pricesort='.format(str(i)) for i in range(1,3)]
headers={
    'user-agent':'Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/96.0.4664.93 Safari/537.36'
}
for url in urls:
    html=requests.get(url,headers=headers)
    selector=etree.HTML(html.text)
    infos=selector.xpath('//div[@class="imgInfo"]')
    for info in infos:
        name=info.xpath('/html/body/div[4]/div[1]/div[2]/ul/li/div[1]/div/p/a/text()')[0]
        price=info.xpath('/html/body/div[4]/div[1]/div[2]/ul/li/div[2]/div[1]/span/text()')[0]
        address=info.xpath('/html/body/div[4]/div[1]/div[2]/ul/li/div[2]/p[2]/a/text()')[0]
        #time=info.xpath('')[0]
        writer.writerow((name,price,address))
f.close()

但在更换网址后就没有问题

for url in urls:
    html = requests.get(url, headers=headers)
    selector = etree.HTML(html.text)
    infos = selector.xpath('//div[@class="imgInfo"]')
    num = 0
    for info in infos:
        name = info.xpath('/html/body/div[4]/div[1]/div[2]/ul/li/div[1]/div/p/a/text()')[num]
        price = info.xpath('/html/body/div[4]/div[1]/div[2]/ul/li/div[2]/div[1]/span/text()')[num]
        address = info.xpath('/html/body/div[4]/div[1]/div[2]/ul/li/div[2]/p[2]/a/text()')[num]
        num += 1
