Newspaper3k export to csv on first row only-CodePudding

With the help of 'Life is complex' I have managed to scrape data from CNN newswebsite. The data (URLs) extracted from are saved in a .csv file (test1). Note this had been done manually as it was easier to do!

from newspaper import Config
from newspaper import Article
from newspaper import ArticleException
import csv

USER_AGENT = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:78.0) Gecko/20100101 Firefox/78.0'

config = Config()
config.browser_user_agent = USER_AGENT
config.request_timeout = 10

with open('test1.csv', 'r') as file:
    csv_file = file.readlines()
    for url in csv_file:
        try:
            article = Article(url.strip(), config=config)
            article.download()
            article.parse()
            print(article.title)
            article_text = article.text.replace('\n', ' ')
            print(article.text)
        except ArticleException:
            print('***FAILED TO DOWNLOAD***', article.url)
            
with open('test2.csv', 'a', newline='') as csvfile:
    headers = ['article title', 'article text']
    writer = csv.DictWriter(csvfile, lineterminator='\n', fieldnames=headers)
    writer.writeheader()
    writer.writerow({'article title': article.title,
                     'article text': article.text})

With the code above I manage to scrape the actual news information (title and content) from the URLs and also to export it to a .csv file. Only the issue with the export is, is that it only exports the last title and text (therefore I think it keeps overwriting the info on the first row)

How can I get all the titles and content in the csv file?

Thanks for giving me a shout out.

The code below should help you solve your CSV write issue. If it doesn't just let me know and I will rework my answer.

P.S. I will update my Newspaper3k overview document with more details on writing CSV files.

P.P.S. I'm current writing a new news scraper, because the development for Newspaper3k is dead. I'm unsure of the release date of my code.
