You have to many occurences because that regex matches XXXxXXX, but also
XXxXX. You should only match exactly 3 guards on each side. IIRC
I used something like (sadly I threw my code for levels 1 and 2 away):
'[^A-Z][A-Z]{3}[a-z]{1}[A-Z]{3}[^A-Z]'

Doesn't the {3} mean a minimum of 3?
I may be wrong, its not a feature I use much but I thought there was a
gotcha with the {} notation that meant you had to provide a
terminating
character too?

Hey Liam thanks again for the hint. I have finally managed to use the ???trans function. But now apply it to the URL, I am lost again. (I did apply it to the URL-twice) but nope, nothing is happening. One more hint if possible. Thanks JC ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

It's exactlu equivalent to [A-Z][A-Z][A-Z]

If you want to prevent e.g. 'ABCDE' from matching as opposed to only
'BCD', yes, you need some kind of terminator.

This is what I did. I have tried the whole field, part of the URL (after the .com), etc.. I Just get the old 404 not found message. JC ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

copied the URL, paste it in my script in Python and run it (once) did not get nowhere, then did it a second time, and again did not get nowhere. JC ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

???trans function. But now apply it to the URL, I am lost again. Its not strictly accurate, it means apply it to a section of the address... Alan G. (I'm catching up! All the previous posts help of course :-) ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Python Challenge - Riddle 2
Hi John, took me awhile to solve this one too, it's quite good, teaches you about a part of Python that you wouldn't normally use. Do you want hints or spoilers? I've give hints for now, search the Python docus for 'trans', check the string methods. Hope that didn't make it too obvious. Now, if anybody can assist me with problem 3...

Re: [Tutor] Python Challenge - Riddle 2
Hmmm... the forums don't overly explain level 3. Am I looking for something like this - XXXjXXX? or something like XjXX or XXjX? I've also looked for - ooXXXoo XXXjXXXooXXXoo and oooXooo oooXooo oooXooo XXXjXXX oooXooo oooXooo oooXooo Argh. My head is going to explode.

Re: [Tutor] Python Challenge - Riddle 2
Am I looking for something like this - XXXjXXX? or something like XjXX or XXjX? The former: 3 on each side. Exactly 3. BTW wink, you can check your understanding by saving the image you get from riddle 6, compressing it with zlib, filtering out all but string.letters and looking for the same pattern as in riddle 2. You should come up with scdehtinjgu...but that's a 404 for a web page. /c ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
