the problem is here that
a = 12,123
will actually create a tuple with two elements (namely 12 and 123):
>> a = 12,123
Converting this to a string yields '(12, 123)', which is not what you
want (sounds confusing, bit soon you'll see how many amazing things
can be done like this :-)
>> a = "12,123"
>> a = int(a.replace(',', ''))
I don't know the urllib, but I suppose if you use it to fetch content
from a web page it will return strings anyway.
