Re: newbie question

Hi sharon,

the problem is here that
a = 12,123
will actually create a tuple with two elements (namely 12 and 123):

>a = 12,123
>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 :-)

Try:

>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.

Traceback (most recent call last):

ValueError: invalid literal for int() with base 10: '(12 123)'

the comma has become an empty space, it cannot be converted to an
integer. i try the above in a winxp python command line.

Strings have a replace method. Calling replace(",", "") on the
string will do the trick here.
