The interactive interpreter is a good tool to try to access various elements 
in the "soup":

$ python -i yourcode.py # enter the interpreter when your script terminates
[snip] 
<td class="odds" data-odd="3.48"></td>
<td class="odds best-betrate" data-odd="2.04"></td>
>>> 
>>> odd
<td class="odds best-betrate" data-odd="2.04"></td>
>>> odd.attrs["data-odd"]
'2.04'

If you want to do calculations you have to convert the string to a number 
first:

>>> float(odd.attrs["data-odd"])
2.04

You probably want the match, too, so it may be better to go for the <tr> 
elements in the first table:

>>> for tr in soup.table.find_all("tr", class_="strong"):                                         
...     print tr.find(class_="first-cell").string,
...     print float(tr.find(class_="odds").attrs["data-odd"]) 
... 
Aston Villa - Burnley 2.2
Crystal Palace - Swansea 1.81
