CSV为每个条目留下一个空白行[重复]

import praw
import configReddit
import csv

reddit = praw.Reddit(
    client_id=configReddit.client_id,
    client_secret=configReddit.client_secret,
    password=configReddit.password,
    user_agent=configReddit.user_agent,

        print(comment.body)
        comment_writer.writerow([comment.body])
