向MySQL选项卡添加多个数组

Question

我写了一个脚本，可以从多个URL中提取有用的信息，在BeautifulSoup的帮助下添加到两个数组（id和names）中，然后将这些数组的值添加到一个MySQL表中，其中ids[0]和names[0]是表的第0行，依此类推。。。你知道吗

然而，我的代码非常难看，我相信有一种方法比我的更好。你知道吗

谁能给我一个提示吗？我特别需要一个关于如何通过两个数组进行迭代的输入。。。你知道吗

提前谢谢！你知道吗

#!/usr/bin/env python
from bs4 import BeautifulSoup
from urllib import urlopen
import MySQLdb 

#MySQL Connection
mysql_opts = {
    'host': "localhost",
    'user': "********",
    'pass': "********",
    'db':   "somedb"
    }
mysql = MySQLdb.connect(mysql_opts['host'], mysql_opts['user'], mysql_opts['pass'], mysql_opts['db']) 

#Add Data SQL Query
data_query = ("INSERT INTO tablename "
               "(id, name) "
               "VALUES (%s, %s)")

#Urls to scrape
url1  = 'http://somepage.com'
url2  = 'http://someotherpage.com'
url3  = 'http://athirdpage.com'

#URL Array
urls = (url1,url2,url3)

#Url loop
for url in urls:
    soupPage = urlopen(url)
    soup = BeautifulSoup (soupPage)

    ids = soup.find_all('a', style="display:block")
    names = soup.find_all('a', style="display:block")

    i = 0
    print ids.count
    while (i < len(ids)):
        try: 
            id = ids[i]
            vid = id['href'].split('=')
            vid = vid[1]
        except IndexError:
            id = "leer"

        try:
            name = names[i]
            name = name.contents[0]
            name = name.encode('iso-8859-1')
        except IndexError:
            name = ""

        data_content = (vid, name)
        cursor.execute(data_query, data_content)
        emp_no = cursor.lastrowid
        i = i + 1

Answer 1

我的评论似乎就是答案。刚刚测试过：

for vid, name in zip(ids, names):
        vid = vid['href'].split('=')
        vid = vid[1]

        name = name.contents[0]
        name = name.encode('iso-8859-1')

        data_content = (vid, name)
        cursor.execute(data_query, data_content)
        emp_no = cursor.lastrowid

抱歉，重复了。 如果有人能给答案添点什么，请随便。你知道吗
