[plaid2017]pykemon

rename할때 {0.pykemon}을 넣는다

python의 format함수를 이용해서 return을 해줄때 입력에 formatstring을 주입할 수 있다.

{0.__class__}를 하면 format의 class정보를 릭할 수 있는데

{0.pykemon}을 넣으면 아래와 같이 format에 Pykemon클래스가 들어있었기 때문에  있는 Pykemon.pykemon의 정보가 쭈루룩 나온다.

소스코드를보면

(p 는 Pykemon class변수)

    if not p:

        return "Error: trying to name a pykemon you haven't caught!"

    

    r = session.get('room')   

    s = session.get('caught')

    for pykemon in s['pykemon']:

        if pykemon['pid'] == name:

            pykemon['nickname'] = new_name

            session['caught'] = s

            print session['caught']

            return "Successfully renamed to:\n" + new_name.format(p)
