Level 3

This was a tricky one, but got it in the end. The hints given the past couple of posts helped me see past my mistake

I see alot of people want to use the re module, while it is very slick, I solved this one without it. A simple for loop to iterate through and check for the patter will do it. The main key is the "exactly" hint. this will not work: XXXxXXX, this will: xXXXxXXXx

Thanks

I feel like I understand the challenge, but I only find 5 Capital letters (TOLYD) after stepping through the pages 400 times. Everyone else seems to have issues with searching, but I'm not even getting anything to really search through.

I'm just searching through the "and the next nothing is" from the 400 pages, is there some other text I should record while doing that?

I've been thinking more about this and I think it may have something to do with when I'm prompted to "divide by two and keep going". I dealt with this by using regular expressions to find "nothing is" and dividing by two if those words weren't found. Unfortunately I can't really see specifically how that would screw something up without giving me an error..

Any advice would be appreciated, I'm a bit lost at this point.

Thanks,

Err... this is the thread for Level 3, and you seem to be asking about Level 4...

Hint: you will have TEN sequences of characters which match the condition. Take one small letter from each of the matches, and...

Got all confuzed with the previous answers, but this helped me out. I already had the ten solutions and had tried them all as .html in the URL but got nothing, thanks

If you are too lazy to write scripts, try this online tool:

http://www.pythonregex.com/

Does it has 10 letters? i think i've got it,but when i paste it to the url,the page changed to be a empty page

I got 10 characters which look perfect. However, when I tried to http://www.pythonchallenge.com/pc/def/(word I got).html, just went to (myword.php)
Give the fist 6 characters: linked****
right or not?

I got the same with you...

and also return 'xxxxx.php'

I have the same problem! Can anybody tell in which format we need to put the phrase in the url??

Problem fixed! This blank page isn't there by mistake

Hello

I have made this:

  Code:

challenge = open('challenge2.txt')
regel = challenge.read()
uitkomst = re.search(/[A-Z]{3}/[a-z]/[A-Z]{3})
print uitkomst


I never worked with regex. I only worked with the book "Thinking like a scientist"

But when I try this I see this error message :
SyntaxError: invalid syntax

Can someone give me a hint where I can find a good tutorial how to search for this ?

Regards,

Roelof

This was a good one! Took me a while but I finally figured it out and learned a new thing or two about RE's!

A couple of hints that helped me:

1. Read up on regular expressions: http://www.regular-expressions.info/tutorial.html; this was helpful in getting the lay of the land. What I suddenly realized is you get EXACTLY what you ask for in RE's. Like so many others in this forum, I wound up with 477 results. When I read this tut, and did a few simple patterns by hand, that is when I figured out that I was not just matching patterns of the form 'XXXxXXX'.

2. The python docs on the re module: http://docs.python.org/library/re.html#

After reading the above, that is when things clicked. I should have done that first instead of plunging into coding; I would have saved myself a lot of heart ache solving this one.

Ugh, the clue is misleading: "One small letter, surrounded by EXACTLY three big bodyguards on each of its sides" does NOT mean one small letter, three big letters, one small letter, three big letters, one small letter; it simply means three big letters, one small letter, three big letters.

If this is the quality of the clues we are working with, I will give up. It's no fun to play a game with underspecified puzzles.

It's VERY specific. "One small letter surrounded by at AT LEAST three bodyguards" != "One small letter surrounded by EXACTLY three bodyguards".

If this is the quality of the clues we are working with, I will give up. It's no fun to play a game with underspecified puzzles.

I'll admit, there are a couple of those, but they're around level 20. Most of them are straight logic and programming challenges.

EXACTLY 3! Think carefully! And Thanks everyone!
