從 Python 中的鏈接中提取標題（美麗的湯）

Question

我是 Python 的新手，我希望從鏈接中提取標題。 到目前為止，我有以下內容，但遇到了死胡同：

import requests
from bs4 import BeautifulSoup
page = requests.get("http://books.toscrape.com/")
soup = BeautifulSoup(page.content, 'html.parser')
books = soup.find("section")
book_list = books.find_all(class_="product_pod")
tonight = book_list[0]

for book in book_list:
    price = book.find(class_="price_color").get_text()
    title = book.find('a')
    print (price)
    print (title.contents[0])

Answer 1

要從鏈接中提取標題，您可以使用title屬性。

例如：

import requests
from bs4 import BeautifulSoup
page = requests.get("http://books.toscrape.com/")
soup = BeautifulSoup(page.content, 'html.parser')

for a in soup.select('h3 > a'):
    print(a['title'])

印刷：

A Light in the Attic
Tipping the Velvet
Soumission
Sharp Objects
Sapiens: A Brief History of Humankind
The Requiem Red
The Dirty Little Secrets of Getting Your Dream Job
The Coming Woman: A Novel Based on the Life of the Infamous Feminist, Victoria Woodhull
The Boys in the Boat: Nine Americans and Their Epic Quest for Gold at the 1936 Berlin Olympics
The Black Maria
Starving Hearts (Triangular Trade Trilogy, #1)
Shakespeare's Sonnets
Set Me Free
Scott Pilgrim's Precious Little Life (Scott Pilgrim #1)
Rip it Up and Start Again

Answer 2

你可以使用它：

import requests
from bs4 import BeautifulSoup
page = requests.get("http://books.toscrape.com/")
soup = BeautifulSoup(page.content, 'html.parser')
books = soup.find("section")
book_list = books.find_all(class_="product_pod")
tonight = book_list[0]

for book in book_list:
    price = book.find(class_="price_color").get_text()
    title = book.select_one('a img')['alt']
    print (title)

Output：

A Light in the Attic
Tipping the Velvet
Soumission
Sharp Objects
Sapiens: A Brief History of Humankind
The Requiem Red...

只需修改現有代碼，您就可以使用包含示例中書名的替代文本。

print (title.contents[0].attrs["alt"])
