# Python Challenge - Level 14

## Problem ## Clues

### Clue 1

In HTML source code:

<!-- remember: 100*100 = (100+99+99+98) + (...  -->

<img src="wire.png" width="100" height="100" />

This is the image: ### Clue 2

Title of the HTML:

walk around

### Clue 3

The image of the problem: we are looking at(for) something spiral!

## Exploration

Do not be fooled by that barcode-like image, it appears to be a square, that is because in HTML both the width and height are set as 100.

>>> from PIL import Image
>>> im = Image.open('../images/wire.png')
>>> im.size
(10000, 1)

The real size is not 100*100! It is 10000*1!

Based on all the clues, our assumption is to use the 10000 points from the given image, create another image of 100*100, by walking around the square from outside to inside, so we go right for 100 pixels, then down 99 pixels, then left 99 pixels, then up 98 pixels(clue 1).

## Solution

from PIL import Image
im = Image.open('wire.png')
delta = [(1,0),(0,1),(-1,0),(0,-1)]
out = Image.new('RGB', [100,100])
x,y,p = -1,0,0
d = 200
while d/2>0:
for v in delta:
steps = d // 2
for s in range(steps):
x, y = x + v, y + v
out.putpixel((x, y),im.getpixel((p,0)))
p += 1
d -= 1
out.save('level_14_result.jpg') It's a cat!
