我正在使用 BS4 和 python2.7。这是我的代码的开始（感谢root）：
from bs4 import BeautifulSoup
import urllib2
f=urllib2.urlopen('http://yify-torrents.com/browse-movie')
html=f.read()
soup=BeautifulSoup(html)
当我打印 html 时，它的内容与在 chrome 中查看的页面的来源相同。然而，当我打印汤时，它会切掉整个身体并留下这个（头部标签的内容）：
<!DOCTYPE html>
<html>
<head>
<title>Browse Movie - YIFY Torrents</title>
<meta charset="utf-8">

我哪里错了？！
