how to solve list index out of range error Python?

I'm learning web scraping using python.

Here is my first python code

# encoding=utf8
import urllib2
from bs4 import BeautifulSoup


soup = BeautifulSoup(urllib2.urlopen("http://www.bcsfootball.org/").read(),"lxml")

for row in soup("table", {'class': "mod-data"})[0].tbody("tr"):
    tds = row('td')
    print tds[0].string, tds[1].string

I'm getting error

/usr/bin/python2.7 /home/NewYork/PycharmProjects/untitled/News.py
Traceback (most recent call last):
  File "/home/NewYork/PycharmProjects/untitled/News.py", line 8, in <module>
    for row in soup("table", {'class': "mod-data"})[0].tbody("tr"):
IndexError: list index out of range

Can anyone help me what am doing wrong ?

And one more thing I would like to ask ...please help me to understand what is happening here exactly...

for row in soup("table", {'class': "mod-data"})[0].tbody("tr"):

Thanks !! :)

This would give you the expected result:

import urllib2
from bs4 import BeautifulSoup


soup = BeautifulSoup(urllib2.urlopen("http://www.bcsfootball.org").read(),"html")

welcome = soup("div", {'class': "col-full"})[1] # we know it's index 1


for item in welcome:
   print item.string

The error message means soup("table", {'class': "mod-data"}) is an empty list, but you want to get the first element in this list.

You should ensure the table element has a node using class "mod-data".
