Python中如何将爬取到的数据循环存入到csv文件中？

问题描述

求大神指导 再此感激不尽！！！

我想要把输出的结果存入到csv文件中

我的代码如下：（Python 需要3.5版本的）

# coding:utf-8import requestsimport jsonimport timetime_unix = time.time()time_unix = str(time_unix).split(’.’)[0]headers = { ’Host’: ’sec.wedengta.com’, ’User-Agent’: ’Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/53.0.2785.113 Safari/537.36’, ’Connection’: ’keep-alive’, ’Content-Language’: ’zh-CN,zh;q=0.8’, ’Accept’: ’application / json’, # ’Accept-Language’: ’ zh-CN,zh;q=0.8,en-US;q=0.5,en;q=0.3’, ’X-Requested-With’: ’XMLHttpRequest’, ’Referer’: ’https://sec.wedengta.com/findPool.html?dt_from=web&title=%E8%85%BE%E8%AE%AF%E6%B6%A8%E5%81%9C%E6%9D%BF%E9%A2%84%E6%B5%8B%20-%20%E5%8E%86%E5%8F%B2%E6%8E%A8%E8%8D%90&id=99970_56&webviewType=userActivitesType&dt_page_type=11&timeStamp=1488801827765&barType=null&accessp=null’, ’Accept-Encoding’: ’gzip, deflate, br’ }url = ’https://sec.wedengta.com/getIntelliStock?action=IntelliSecPool&id=99970_56&_={0}’.format(time_unix)request = requests.get(url, headers=headers)temp = str(json.loads(request.text)).replace(’’, ’’)dic = eval(temp)content = dic[’content’]content = eval(content)vtDaySec = content[’vtDaySec’]for every in vtDaySec: for every_company in every[’vtSec’]:print(every[’sOptime’])print(every_company[’sChnName’])print(every_company[’sDtCode’][4:])print(’n’)

运行出来结果截图：
