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

加一个变量
