python脚本 - 将单词分组为If-Not语句

问题描述:

试图找出如何使用if语句,在该语句中,我可以将三到四个单词分组,以便从CSV文件中省略。在代码底部,您会看到我卡在:if ('reddit', 'passwords') not in x:python脚本 - 将单词分组为If-Not语句

任何帮助都会很棒。

# import libraries 
import bs4 
from urllib2 import urlopen as uReq 
from bs4 import BeautifulSoup as soup 

my_url = 'https://www.reddit.com/r/NHLStreams/comments/71uhwi/game_thread_sabres_at_maple_leafs_730_pm_et/' 

# opening up connection, grabbing the page 
uClient = uReq(my_url) 
page_html = uClient.read() 
uClient.close() 

# html parsing 
page_soup = soup(page_html, "html.parser") 


filename = "sportstreams.csv" 
f = open(filename, "w") 
headers = "Sport Links " + "\n" 
f.write(headers) 

links = page_soup.select("form a[href]") 
for link in links: 
    href = link["href"] 
    print(href) 

    f.write(href + "\n") 



with open('sportstreams.csv') as f,open('sstream.csv', "w") as f2: 
    for x in f: 
     if ('reddit', 'passwords') not in x: # trying to find multi words to omit 
      f2.write(x.strip()+'\n')

目前还不清楚你想要什么'如果(...)不在x'中做。所有的元素都必须从'x'中丢失,或者它们中的任何一个足以触发'if'? –

我想我的代码很弱,因为我试图用任何包含单词“reddit”“/ r /”和“/ password”的行来简化我的结果以省略。这将缩短我的链接列表,这对我来说是成功的。 :) –

请编辑您的问题的解释,使其完成。如果你能够展示你想要忽略的行与你想要保留的行的具体例子,那将是很好的。 –

使用内置函数all

if all(t not in x for t in ('reddit', 'passwords')): 

或者any

if not any(t in x for t in ('reddit', 'passwords')): 

这是它是在你的情况管理器:

with open('sportstreams.csv') as f, open('sstream.csv', "w") as f2: 
    for line in f: 
     if any(t in line for t in ('reddit', 'passwords')): 
      # The line contains one of the strings. 
      continue 
     else: 
      # The line contains none of the strings. 
      f2.write(line.strip() + '\n') 
+0

这不是我的朋友。我可能做错了什么?我用你写的东西替换了'if('reddit','passwords')不在x:'中。不要忽略包含reddit或密码的行。 :( –

@JamesDean这部分是你自己的错,你的问题中的规格是非常不清楚的 –

我很抱歉,我应该怎样做,以忽略任何包含这些元素的行(reddit,/ r /,/ password)? –
