    http://www.pythonchallenge.com/pc/def/integrity.html 문제 페이지에서 접속하면 파리같이 생긴 곤충의 그림이 나오고 소스를 보면 어떤 인코딩 된듯한 문자열이 나온다. 이후에 알게 되었지만 사진속의 곤충은 벌이였고 beezip을 의도한 것으로 보인다. #!c:\python26\python.exe import bz2 un = 'BZh91AY&SYA\xaf\x82\r\x00\x00\x01\x01\x80\x02\xc0\x02\x00 \x00!\x9ah3M\x07<]\xc9\x14\xe1BA\x06\xbe\x084' pw = 'BZh91AY&SY\x94$|\x0e\x00\x00\x00\x81\x00\x03$ \x00!\x9ah3M\x13<]\xc9\x14\xe1BBP\x91\xf08' print repr(bz2.decompress(un)) print repr(bz2.decompress(pw))
