Apple iTunes StoreのデータをPythonから利用する

前回のエントリーでsimplejsonをインストールしてPythonからJSONを使いたいな〜〜〜と思ったのは、

JSON形式のデータフォーマットで提供されているApple iTunes Store内のアーティストデータを、Pythonで利用したいな〜〜〜と思ったからなのですが、

iTunes Store内のアーティストデータは、iTunes StoreのWeb APIを使って、例えば、以下のような感じで利用することが出来ます。

【例】iTunes Storeからamazarashiのデータを引っ張って来る。（やっつけソースですが。。。）

from urllib2 import *
import simplejson as json　　（← Python2.6 以降を使える場合はここは「import json」 ）
from StringIO import StringIO
conn = urlopen('http://ax.phobos.apple.com.edgesuite.net/WebObjects/MZStoreServices.woa/wa/wsSearch?term=amazarashi&country=JP&lang=ja_jp&media=music')
j=json.load(StringIO(conn.read()))
for i in range( int( j['resultCount'] ) ):
    print 'No.', i + 1
    for key in sorted(j['results'][i].keys()):
        data = j['results'][i][key]
        if key == 'artworkUrl100':
            print '<img src="' + data + '">'
        print key, " ==> ", data

【結果】
