我正在尝试使用beautifulsoup4和requests库抓取网站

Question

我想从这个网站上提取电影的名称，年份和长度

代码如下：

import requests
from bs4 import BeautifulSoup

URL = 'https://www4.f2movies.to'
page = requests.get(URL)
soup = BeautifulSoup(page.content, 'html.parser')

#Trending Movies
Movies = []
Year = []
Length = []

for a in soup.findAll('a', href=True, attrs={'class':"film-detail film-detail-fix"}):
    name=data.find('div', href=True, attrs={'class':'film-name'})
    year=data.find('span', href=True, attrs={'class':'fdi-item'})
    length=data.find('span', href=True, attrs={'class':'fdi-item fdi-duration'})
    Movies.append(name.text)
    Year.append(year.text)
    Length.append(length.text)

print(Movies)
print(Year)
print(Length)

我得到的结果如下所示：

(Projects) anildhage@xxx-MacBook-Air WebScrape % python scrape.py
[]
[]
[]
(Projects) anildhage@xxx-MacBook-Air WebScrape % 

有没有人能建议我哪里错了？提亚

你的一些选择器在使用find()时是不正确的。要获取所有数据，请使用以下示例：

import requests
from bs4 import BeautifulSoup

URL = "https://www4.f2movies.to"
page = requests.get(URL)
soup = BeautifulSoup(page.content, "html.parser")

# Trending Movies
Movies = []
Year = []
Length = []

for data in soup.findAll("div", attrs={"class": "film-detail film-detail-fix"}):
    name = data.find("h3", attrs={"class": "film-name"})
    year = data.find("span", attrs={"class": "fdi-item"})
    length = data.find("span", attrs={"class": "fdi-item fdi-duration"})
    if not length:
        continue

    Movies.append(name.text.strip())
    Year.append(year.text)
    Length.append(length.text)


print(Movies)
print(Year)
print(Length)

输出：
