python爬虫数据写入csv文件中文乱码，用’utf-8‘在pycharm中打开文件没有问题，但是用excel打开却出现了问题，以下为解决方法。
（最近在练习爬虫，这个博文是对自己学习的记录和分享，如果有问题，非常感谢各路大佬指出！！！）
for r in result:r_lis=[] #方法二：将爬到的内容储存在csv文件中r_lis.append(r.text)with open('company.csv','a',newline='',encoding='utf-8-sig') as csvfile:spamwriter=csv.writer(csvfile, delimiter=',')spamwriter.writerow(r_lis)
在with自开合那里加入newline='',encoding='utf-8-sig'是关键
以下是天眼查的爬虫
