Bash vs Python

A simple case study:
It's not about one programming language killing and replacing the other, its all about the purpose!

The scenario:
Using convert to resize images, both in bash and python just for the fun of it.

First up is BASH:

<b><pre style='color:#000000;background:#ffffff;'>mkdir -p resized
find <span style='color:#7f0055; font-weight:bold; '>.</span> -name <span style='color:#2a00ff; '>'*.jpg'</span> -or -name <span style='color:#2a00ff; '>'*.png'</span> -or -name <span style='color:#2a00ff; '>'*.gif'</span><span style='color:#2a00ff; '>\</span>
-<span style='color:#7f0055; font-weight:bold; '>exec</span>  convert -resize 648x480 <span style='color:#2a00ff; '>'{}'</span><span style='color:#2a00ff; '>\</span>
<span style='color:#2a00ff; '>"resized</span><span style='color:#3f3fbf; '>/</span><span style='color:#2a00ff; '>$(basename '{}')"</span> <span style='color:#2a00ff; '>';'</span>
</pre>

Its Pythons turn: 

from glob import glob
from os.path import splitext
from os import system
if not path.exists('resized'):
mkdir('resized')
for pic in glob.glob('*'):
if os.path.splitext(pic)[1] in ext:
system('convert -resize 640x480 "%s" "resized/%s"'
% (pic,os.path.splitext(pic)[0]))
