my soup.find_all is not finding anything: it runs into a empty-list

[apollo]

hi there

i use python to do some beginner-webscraping.
i am using a simple basic-script that captures stock price data: the nice thing it should do this in real time, and then it should updating it self.



At the moment i have found out some issues: my soup is finding a empty list -

import bs4

import requests

from bs4 import BeautifulSoup



def parsePrice():

`r=requests.get('`[`http://finance.yahoo.com/quote/FB?p=FB`](http://finance.yahoo.com/quote/FB?p=FB)`')`

`soup=bs4.BeautifulSoup(r.text,"xml")`

`price=soup.find_all('div',{'class':'My(6px) Post(r) smartphone_Mt(6px)'})[0].find('span').text`

`return price`


while True:

`print('the current price_ '+str (parsePrice()))`

Traceback (most recent call last):

File "C:\Users\Kasper\Documents\_f_s_j\_mk_\_dev_\bs\yahoo_finance.py", line 14, in <module>

print('the current price_ '+str (parsePrice()))

File "C:\Users\Kasper\Documents\_f_s_j\_mk_\_dev_\bs\yahoo_finance.py", line 10, in parsePrice

price=soup.find_all('div',{'class':'My(6px) Post(r) smartphone_Mt(6px)'})[0].find('span').text

IndexError: list index out of range

after musing some time i saw: well my soup.find_all is not finding anything: This causes the [0] since it is quite out of range because the find_all returns an empty list.
