使用python从链接中删除/url？q=

首先，我对python比较陌生，所以我写的这个程序可能不是最有效的，但我遇到了一个问题。我的程序应该是获取有关科罗纳的新闻，并打印标题以及新闻网站的链接。我已经设法让它打印标题和链接，但是链接上的输出总是在

https://

之前包含

/url？q=

代码如下：

import requests
from bs4 import BeautifulSoup
import re

#Fetching the site
r = requests.get('https://www.google.com/search?q=corona+nyheter&source=lnms&tbm=nws&sa=X&ved=2ahUKEwiJ5eut64ztAhUliIsKHVyJDwIQ_AUoAXoECA0QAw&biw=1920&bih=1127')
src = r.content

#Letting soup do its thing
soup = BeautifulSoup(src, 'lxml')
data_text = soup.find_all('div', attrs={'class':'BNeawe vvjwJb AP7Wnd'})
data_link = soup.find_all('div', attrs={'class':'kCrYT'})

#Printing the titles of the news
for i in range(0, len(data_text)):
    print(str(i) + '.'+ data_text[i].text)

#Looking for links inside of the div with the class 'kCrYT'
links = []
for i in range(0, len(data_link)):
    for link in data_link[i].find_all('a'):
        links.append(link.get('href'))

#Printing each link
for i in range(0, len(links), 2):
    print(links[i])
    print('')

#print(data_link[0])
#print(dir(data_link[0]))

标题工作正常。问题是链接的输出，即：

/url?q=https://www.svt.se/nyheter/utrikes/200-anstallda-smittade-med-corona-pa-minkfarmar-i-danmark&sa=U&ved=2ahUKEwjzgJeEgo3tAhXT7HMBHf9BAYsQxfQBMAF6BAgHEAE&usg=AOvVaw1bQmvySzBxBofyWJgMx6L_

但是我不知道如何删除链接的

/url？q=

部分。

感谢您的帮助。

有很多方法可以做到这一点；如果保证将处理的每个字符串的开头都会出现相同的7个字符，那么最简单的方法就是应用子字符串操作：

link = "/url?q=https://www.svt.se/nyheter/utrikes/200-anstallda-smittade-med-corona-pa-minkfarmar-i-danmark&sa=U&ved=2ahUKEwjzgJeEgo3tAhXT7HMBHf9BAYsQxfQBMAF6BAgHEAE&usg=AOvVaw1bQmvySzBxBofyWJgMx6L_"
clean_link = link[7:]
print(clean_link) # https://www.svt.se/nyheter/utrikes/200-anstallda-smittade-med-corona-pa-minkfarmar-i-danmark&sa=U&ved=2ahUKEwjzgJeEgo3tAhXT7HMBHf9BAYsQxfQBMAF6BAgHEAE&usg=AOvVaw1bQmvySzBxBofyWJgMx6L_

您可以

拆分（）

链接

/url？q=

，并打印第二个索引：

# Printing each link
for i in range(0, len(links), 2):
    print(links[i].split("/url?q=")[1])
    print('')

输出：

lstrip

将从字符串开头删除已定义的字符（如果字符串以这些字符开头）

因此，只需在字符串上执行

.lstrip（“/url？q=”）

。

尝试

.lstrip（“/url？q=”）
