Thanks for the explanation. It's clearer now.

OK, I'll assume you understand the basic for loop structure
and focus on the function call:
soup('table', {'class' : 'spad'})[0].tbody('tr')
Ignore the bit at the end for now:
soup('table', {'class' : 'spad'})
Thats a call to a function taking a string and a dictionary as
arguments.
The string says we want to look for table tags. And the dictionary
says
we want tables that have an attribute class with a value spad.
Is that bit clear?
Then we add an index [0] to get the first table.
Finally we call tbody("tr") to extract the tr tags from the table.
The for loop thus iterates over the rows of the first table with
class=spad.
There might be slightly more to it than that, its a long time since I
played with BS...

Ah, in that case you should definitely read the tutorial.
