Tutor maillist - Tutor (AT) python (DOT) org

Man! I was thinking that it was simple. This is a little bit hard
but will try to make sense of it as I can.

K, the way this list operates is that you try to solve it yourself.
When it doesn't work you tell us what you tried to do and what
went wrong. We then try to point you in the right direction.

Thank you for your assistance. I'm glad you're up there to assist.

The tutor list are all here waiting to help. We are like any good
teacher, we don't just give answers out will-nilly but we do try
to steer you to the solution so that you understand it for the future.

If you do have a problem post the code that causes the problem
and also paste in any error messages you get - the whoile error
not just the last line.

Have a go, let us see what is sticking you, we are here to help,

How would you fetch the shapefile with your browser? Is there a url to
download the file? It's pretty simple to fetch a web page or other
resource from a URL and save it to a local file. urllib.urlretrieve()
will do it.

If you have to authenticate (login) to the web site it gets a little
more complex. urllib2 is similar to urllib but it has more options and
supports authentication. There is a tutorial for urllib2 here:

Thank you for your assistance. I'm glad you're up there to assist.
