Strange outcome using enumerate()

Oct 25th, 2009

I have to make some bookmarks so I quickly knocked up the script below and ran it. It created the files fine but with a with an incorrect ip in the second file

The second bookmark created should be named York.URL which it is but the ip address of the url is 192.65.0.95 where it should be 192.65.2.95. It uses the enumerate value and adds 1 each time.

I'd imagine I'd be able to get the desired outcome by using other methods but what is going on here? Am I missing something obvious?

This little test code works fine ...

... and so does your code (removed first line since I am using Python25).
