用python读写和处理csv文件

import requests
from bs4 import BeautifulSoup
import csv

date = open('test.csv', 'w')
writer = csv.writer(date)

url = 'http://www.eastmoney.com/'
req = requests.get(url)
req.encoding = req.apparent_encoding
html = req.text

bf = BeautifulSoup(html, 'lxml')
nlist = bf.find_all(class_ = 'nlist')[0]
a = nlist.find_all('a')
my_list = []
for each in a:
    my_list.append([each.string, each.get('href')])
writer.writerow(['名称', '链接'])
writer.writerows(my_list)
date.close()
