learning plus: python + google GAE + checkIO

python + google GAE + checkIO

底下用就用 checkIO ATM + Google GAE(guestbook) 來當今天的玩具好了. 主要改寫 checkIO ATM 的 input/output parts 跟 GAE 的 db handle 部分. 除了可以練習一下 GAE,也可以玩 checkIO 裡的習題.

input : Web text form
output : results

def checkio_atm(data):
    try:
        data = str(data).replace(' ','').replace('[','').replace(']','')
 datas = [int(d) for d in data.split(",")]
 balance, withdrawal = datas[0], datas[1:-1]
 for a in (0.5 + 1.01*it for it in withdrawal if it %5 ==0):
    balance = floor(balance - a) if balance > a else balance
    return "input = %s, rst = %s" %(data,str(balance))
    except:
     return "CheckIO ATM Error"
