我正在使用feedparser模塊在我的程序中創建新聞提要。 Yahoo!代碼:單獨的RSS提要鏈接/ s
Yahoo! Finance API鏈接元素實際上有兩個鏈接:Yahoo鏈接和實際文章鏈接(外部網站/源)。兩個由一個星號分離,用下面的就是一個例子:
「http://us.rd.yahoo.com/finance/external/investors/rss/SIG=12shc077a/ * http://www.investors.com/news/technology/click/pokemon-go-hurting-facebook-snapchat-usage/」
注意兩個項目之間的星號。
我只是想知道是否有pythonic的方式來分開這兩個,只讀第二個鏈接到一個文件。
謝謝你的時間。
這裏是我的相關代碼:
def parse_feed(news_feed_message, rss_url):
''' This function parses the Yahoo! RSS API for data of the latest five articles, and writes it to the company news text file'''
# Define the RSS feed to parse from, as the url passed in of the company the user chose
feed = feedparser.parse(rss_url)
# Define the file to write the news data to the company news text file
outFile = open('C:\\Users\\nicks_000\\PycharmProjects\\untitled\\SAT\\GUI\\Text Files\\companyNews.txt', mode='w')
# Create a list to store the news data parsed from the Yahoo! RSS
news_data_write = []
# Initialise a count
count = 0
# For the number of articles to append to the file, append the article's title, link, and published date to the news_elements list
for count in range(10):
news_data_write.append(feed['entries'][count].title)
news_data_write.append(feed['entries'][count].published)
news_data_write.append(feed['entries'][count].link)
# Add one to the count, so that the next article is parsed
count+=1
# For each item in the news_elements list, convert it to a string and write it to the company news text file
for item in news_data_write:
item = str(item)
outFile.write(item+'\n')
# For each article, write a new line to the company news text file, so that each article's data is on its own line
outFile.write('\n')
# Clear the news_elements list so that data is not written to the file more than once
del(news_data_write[:])
outFile.close()
read_news_file(news_feed_message)
