Getting & instead of & in title return using PRAW

问题

I'm trying to get the top 25 of all time of a given subreddit using PRAW:

import praw
subreddit = 'gamedeals'
r = praw.Reddit(user_agent='getting top 25 of all time by /u/sqrg')
submissions = r.get_subreddit(subreddit).get_top_from_all(limit=25)
titlesFile = open("text.txt", 'w')
for s in submissions:
    titlesFile.write(s.title.encode('utf-8', 'replace') + '\n')
titlesFile.close()

I get the following error:

UnicodeEncodeError: 'ascii' codec can't encode character u'\xa3' in position 63: ordinal not in range(128)

So I changed the line inside the for loop to:

titlesFile.write(s.title.encode('utf-8', 'replace') + '\n')

And it works, but in the text.txt file I get & instead of &. I could change them with some string replace function, but is there any way to directly write the correct title? Also, why did I have to use the encode() method?

回答1:

Enable the setting to decode html entities:

r = praw.Reddit(user_agent='getting top 25 of all time by /u/sqrg')
r.config.decode_html_entities = True
