附加題
- 這個 gold_room 游戲使用了奇怪的方式讓你鍵入數字桑李。這種方式會導致什么樣的 bug导饲？ 你可以用比檢查 0干旧、1 更好的方式判斷輸入是否是數字嗎驹吮？int() 這個函數可以給你一些頭緒剖煌。
這里用了一個判斷輸入的數字是否含1或者0來檢查是否輸入的是數字，很明顯的bug就是避開0和1的數字會被當作非數字來執(zhí)行而芥，例如輸入55
》》》初步的想法律罢，檢測數字的話，用四則運算最直接棍丐，比如15/15=1误辑，于是代碼改為：
def gold_room():
print "This room is full of gold. How much do you take?"
choice = raw_input("> ")
if int(choice) / int(choice) == 1:
how_much = int(choice)
else:
dead("Man, learn to type a number.")
if how_much < 50:
print "Nice, you're not greedy, you win!"
exit(0)
else:
dead("You greedy bastard!")
