问题描述
所以我试图写一个reddit机器人来查找标题中某些单词的文章。这是我到目前为止: top_posts = page.hot(限制= 20)
在top_posts中发布:
title = post.title
如果title.lower()在['word1','word2','word3']:
print(title)
$ c
$ b $ p
$ b $ p $ title.lower():
print(title)
那么它会打印标题中有 word1
的标题,但是当我把它放到列表中时不会。我想用一个列表来匹配同一个单词的不同拼写。我在这里做错了什么?
你有错误地放置操作数的顺序,你做得不对。
使用来检查列表中是否包含任何字词。
('word1','word2','word3']):
print(title)$ b中的wd中的title.lower()中的wd $ b
若要检查中是否包含所有 title
,请使用来代替。
So I'm trying to write a reddit bot to find articles with certain words in the title. Here's what I have so far:
top_posts = page.hot(limit=20)
for post in top_posts:
title = post.title
if title.lower() in ['word1', 'word2', 'word3']:
print(title)
If I replace the last 2 lines with...
if 'word1' in title.lower():
print(title)
then it'll print the titles that have word1
in them but when I put it into a list it won't. I want to use a list to match different spellings of the same word. What am I doing wrong here?
You have the order of the operands wrongly placed and you're not doing it right.
Use any
to check if any of words in the list is contained in the title:
if any(wd in title.lower() for wd in ['word1', 'word2', 'word3']):
print(title)
To check if all of the words are contained in title
, use all
instead.
