start()

编辑:键入一个工作,但2不工作

你这样做gold_room:

next = raw_input('> ')
if '0' in next or '1' in next:
    how_much = int(next)
else:
    dead('man, learn how to type a number')

它只会检查'0' in next or '1' in next,所以"2"不起作用并不奇怪,对吧？

你想要的是这些

next = raw_input('> ')
try:
    how_much = int(next)
except ValueError:
    dead('man, learn how to type a number')

这样做也没有例外也是可能的,但请记住,避免像异常一样重要和基本的东西是一个非常糟糕的主意.我希望这本书至少在以后清楚地表明这一点.

无论如何,所以我们知道int只接受数字,所以我们只需检查:

if next.isdigit():
    how_much = int(next)
