python challenge(8-14)

level8:

the un and pw startswith 'BZh', which is magic number of a bz2 file, so you use bz2 module:

bz2.decompress

level9:

first and second is coordinations of pots.

use ImageDraw.polygon([first],fill=color)

I first tried gnu, then cow, at last bull

level10:

len(a[30]) = ?

a = [1, 11, 21, 1211, 111221, 

the next item is the description of previous item
11 is one 1
21 is two 1
1211 is one two, one one
111221 is one one, one two, two one

level14:

wire.png is a 10000*1 image, convert to 100*100?

consider

remember: 100*100 = (100+99+99+98) + (...

 and title of this level "walk around"

source below:

import Image

def turn():
    global fl,fi,f
    fi=(fi+1)%4
    f=fl[fi]
    
src = Image.open('wire.png')
des = Image.new('RGB', (100,100))

# direction functions
r = lambda (x,y):(x+1,y)
d = lambda (x,y):(x,y+1)
l = lambda (x,y):(x-1,y)
u = lambda (x,y):(x,y-1)

# direction functions list
fl = [r,d,l,u]

# current direction function index
fi = 0

# current direction function
f=r

# current postion
pos = (-1,0)

index = -1
for i in range(100):
    index += 1
    pos = f(pos)
    des.putpixel(pos,src.getpixel((index,0)))
    

for i in range(99,0,-1):
    for m in range(2):
        turn()
        for k in range(i):
            index += 1
            pos = f(pos)
            des.putpixel(pos,src.getpixel((index,0)))
    
des.save('cat.png')
