learn python the hard way ex52 求大神解答

[weixin_36799897]

本人编程小白， 最近在学learn python the hard way ex52, 遇到难题， 我本想用 '*' 来收集在'Laser Weapon Armory'中收集所有错误的输入，从而在web上出现'generic_death'的显示页面，可是，结果却变成了在'Laser Weapon Armory'页面中输入正确的值’999‘无法跳转到下一个场景中，求大神帮忙解答

You're running down the central corridor to the Weapons Armory when a Gothon jumps
out, red scaly skin, dark grimy teeth, and evil clown costume flowing around his 
hate filled body. He's blocking the door to the Armory and about to pull a weapon
to blast you.

While he's laughing you run up and shoot him square in the head
putting him down, then jump through the Weapon Armory door.

You do a dive roll into the Weapon Armory, crouch and scan the room
for more Gothons that might be hiding. It's dead quiet, too quiet.
You stand up and run to the far side of the room and find the
nuetron bomb in its container. There's a keypad lock on the box

hardly any Gothons are on the ship, so your run is clear of

这么长时间了，估计楼主也找到原因，不过既然看到了，就说一下：
# 对输入进行判断
if session.room.name == "Laser Weapon Armory":
if i.action != '999 ':
这个里面多了一个空格，‘999 ’！=‘999’当然不能正常跳转了。

像下面这样，就能够全部正常跳转了：
i = web.input(action=None)
if session.room:
if i.action:
session.room = session.room.go(i.action)
web.seeother('/game')
