        r=requests.get(url)
        r.encoding='utf-8'
        r.raise_for_status
        return r.text
    except:
        return "访问失败"
def getinfo(text,title,price):
    try:

        prices=soup.find_all("div",class_="p-price")
        
        print(type(names))
        print(type(prices))
        for i in range(len(names)):
            title.append(names[i].a.em.text)
            price.append(prices[i].strong.i.text)
    except:

    for i in range(len(namess)):
        print(t.format(i+1,pricess[i],namess[i]))
