Python 3.x '；列表'；对象没有属性'；超时'；并且只打印表中的第一项

我正在尝试从URL列表中提取一个表。当我只输入一个URL时，它只打印出表中的第一个项目，当我向列表中添加更多URL时，我得到错误消息“list”对象没有属性“timeout”。获取其余项目并添加更多URL的最佳方法是什么？ 下面是我正在运行的代码

import time, random, csv, bs4, requests, io
import pandas as pd
timeDelay = random.randrange(5, 20)
from urllib.request import urlopen as uReq
from bs4 import BeautifulSoup as soup

my_urls = [
"https://www.lonza.com/products-services/bio-research/electrophoresis-of-nucleic-acids-and-proteins/nucleic-acid-electrophoresis/precast-gels-for-dna-and-rna-analysis/truband-gel-anchors.aspx",

]
uClient = uReq(my_urls)
page_html = uClient.read()
uClient.close()
page_soup = soup(page_html, "html.parser")

containers = page_soup.findAll('tbody')


product_name_list =[]
cat_no_list = []
size_list = []
price_list =[]

for container in containers:
    if (len(container) > 0):
    #try:
        title_container = container.findAll('td')
        Product_name = title_container[0].text.strip()
        product_name_list.append(Product_name)

        CatNo_container = container.findAll('td')
        CatNo = CatNo_container[1].text.strip()
        cat_no_list.append(CatNo)

        #Size_container = container.findAll('div',{'class':'col-xs-2 noPadding'})
        #Size = Size_container[0].text.strip()
        #size_list.append(Size)

        Price_container = container.findAll('td')
        Price = Price_container[4].text.strip()
        price_list.append(Price)

        print('Product_name: '+ Product_name)
        print('CatNo: ' + CatNo)
        print('Size: ' + 'N/A')
        print('Price: ' + Price)
        print(" ")
        time.sleep(timeDelay)

您正在这里传递一个列表，

uClient=uReq（my\u URL）

作为

my\u URL

，其中需要字符串
您需要传递列表的单个元素，即字符串。

以下是适用于多个URL的已编辑代码

更新的代码（用于获取所有项目）：

你知道为什么它只打印表的第一项而不打印整个表吗？@user9269112我猜你无法正确理解包含数据的标记。在内部，每个项目都在一个标记内。您需要再次迭代项目以获得所需内容。我已经更新了代码来实现我刚才所说的。
