Python:用户输入的Web Scratching

Question

from bs4 import BeautifulSoup
from urllib.request import urlopen as uReq
import requests
url = 'https://en.wikisource.org/wiki/Main_Page'
r = requests.get(url)
Soup = BeautifulSoup(r.text, "html5lib")
List = Soup.find("div",class_="enws-mainpage-widget-content", id="enws-mainpage-newtexts-content").find_all('a')
ebooks=[]
i=0
for ebook in List:
x=ebook.get('title')
for ch in x:
if(ch==":"):
x=""
if x!="":
ebooks.append(x)
i=i+1

print("Please select a book: ")
inputnumber=0
while inputnumber<len(ebooks):
print(inputnumber+1, " - ", ebooks[inputnumber])
inputnumber=inputnumber+1
input=int(input())
selectedbook = Soup.find("href", title=ebooks[input-1])
print(selectedbook)

我想得到用户选择的任何一个的href，但作为输出，我得到：无

有人能告诉我哪里做错了吗

Answer 1

我更改了代码的最后两行，并添加了以下

selectedbook = Soup.find("a", title=ebooks[input-1])
print(selectedbook['title'])
print("https://en.wikisource.org/"+selectedbook['href'])

这很管用！。

注意：find((方法搜索具有指定名称的第一个标记，并返回类型为bs4.element.tag的对象。
