下面是我逐行编写的代码（大约有900 页，每行 10 行和 5 个数据）有什么办法可以使它更快。目前将数据导出到 csv需要80 分钟。有什么方法可以对页面进行并行请求并提高此代码的效率。

import requests
from urllib3.exceptions import InsecureRequestWarning
import csv

requests.packages.urllib3.disable_warnings(InsecureRequestWarning)
from bs4 import BeautifulSoup as bs

f = csv.writer(open('GEM.csv', 'w', newline=''))

    while page_no < 910:
        print('Hold on creating URL to fetch data...')
        url = 'https://bidplus.gem.gov.in/bidlists?bidlists&page_no=' + str(page_no)
        print('URL created: ' + url)
        scraped_data = requests.get(url, verify=False)
        soup_data = bs(scraped_data.text, 'lxml')
        extracted_data = soup_data.find('div', {'id': 'pagi_content'})
        if len(extracted_data) == 0: …
