如何将值从输出传递到python中的字符串

Question

I've been trying to make an application in python and I'm new to python. Well, what I actually want to do is that . I want the feedparser to read the values from an RSS of a website... say reddit... and then I want to make that output as a stringand pass the value further to my code... my code right now..

import feedparser
import webbrowser

feed = feedparser.parse('http://www.reddit.com/.rss')
print feed['entries'][1]['title'] 
print feed['entries'][1]['link'] 

It is working right now.. it parses the feed and I get the output I want... Now, I want to use the "link" from the "print feed['entries'][1]['link'] " and use it in the code further... how can I do so..? To be more specific.. I want to open that URL in my browser... I concluded to something like this..

import feedparser
import webbrowser

feed = feedparser.parse('http://www.reddit.com/.rss')
print feed['entries'][1]['title'] 
print feed['entries'][1]['link'] 

mystring = 'feed['entries'][1]['link']'
webbrowser.open('mystring')

It is of course not working... Please Help... if you need to know anything else.. please let me know...

Answer 1

This is Reddit specific so it won't work on other RSS feeds but I thought this might help you.

from __future__ import print_function
import praw


r = praw.Reddit("my_cool_user_agent")
submissions = r.get_front_page()
for x in submissions:
    print("Title: {0} URL: {1} Permalink: {2}".format(x, x.url, x.permalink))
    print ("------------------------------------------------------------")

For Reddit there are 2 URLs that you might be interested in: the actual link that is submitted (the 'external' link... think imgur, etc) and the permalink to the Reddit post itself.

Answer 2

Instead of passing the feed[entries][1][link] as a string, just pass the value inside to the webbrowser.

Example -

webbrowser.open(feed['entries'][1]['link'])
