为什么如果不工作？

Question

您好我刮雅虎财经，我想打印的股票，如果大于50，但我没有反正这里工作是代码：

import urllib2 
from bs4 import BeautifulSoup as bs4 

list = ["aapl","goog"] 
i = 0 
while i < len(list): 
     url = urllib2.urlopen("http://finance.yahoo.com/q?s="+ list[i] +"&q1=1") 
     soup = bs4(url,"html.parser") 
     for price in soup.find(attrs={'id':"yfs_l84_" + list[i]}): 
       print "something" 
       i += 1 
     if price > 200: 
      print price

你在最后两行缺少的缺口，所以它不是for循环的一部分。另外，您说大于50但代码说200

import urllib2 
from bs4 import BeautifulSoup as bs4 

list = ["aapl","goog"] 
i = 0 
while i < len(list): 
     url = urllib2.urlopen("http://finance.yahoo.com/q?s="+ list[i] +"&q1=1") 
     soup = bs4(url,"html.parser") 
     for price in soup.find(attrs={'id':"yfs_l84_" + list[i]}): 
      print "something" 
      i += 1 
      if price > 50: 
       print price
