Python - 分配打印输出csv

Question

我正在开发一个项目来抓取多个Twitter URL并将其关注者计数分配给csv：

username= ['LazadaPH','ZALORAPH','ShopeePH','eBayPhilippines','beauty_MNL']

for user in username:
   url = 'https://www.twitter.com/'+ user
   r = requests.get(url)
   soup = BeautifulSoup(r.content,'lxml')
   f = soup.find('li', class_="ProfileNav-item--followers")
   title = f.find('a')['title']
   num_followers = int(title.split(' ')[0].replace(',',''))
   print(user,num_followers)

输出如下：

LazadaPH 52841
ZALORAPH 29786
ShopeePH 7004
eBayPhilippines 874
beauty_MNL 2469

因为我对python很新（并且不希望问一个多余的问题）：但是有人可以指导我如何将这个打印输出分配给csv的源和教程，并且必须将它提取到两列（列1是网站字符串，第2列是关注者计数）。

有什么建议？

谢谢你！

Answer 1

你可以使用CSV module

例如：

import csv
with open('out.csv', 'w') as csvfile:
    r = csv.writer(csvfile, delimiter=',')     #   ----> COMMA Seperated
    for user in username:
       url = 'https://www.twitter.com/'+ user
       r = requests.get(url)
       soup = BeautifulSoup(r.content,'lxml')
       f = soup.find('li', class_="ProfileNav-item--followers")
       title = f.find('a')['title']
       num_followers = int(title.split(' ')[0].replace(',',''))
       r.writerow([user,num_followers])    #  ----> Adding Rows

Answer 2

像这样制作你的打印声明：print(user,';',num_followers)它打印';'作为值的分隔符。然后将输出传递给文件：

python yourscript.py > yourcsv.csv
