Learn Python The Hard Way学习(35) - 分支和函数
前面我们已经学习了if，函数，list等，现在我们来转变思路，看看你能理解下面的代码吗？from sys import exitdef gold_room():print "This room is full of fold. How much do you take?"next = raw_input("> ")if "0" in next or "1" in next:how_much = int(next)else:dead("Man, learn to type a number.")if how_much < 50:print "Nice, you are not greedy, you win!"exit(0)else:dead("you greedy bastard!")def bear_room():print "There is a bear here."print "The bear has a bunch of honey."print "The fat bear is in front if another door."print "How are you going to move the bear?"bear_moved = Falsewhile True:next = raw_input("> ")if next == "take honey":dead("The bear looks at you then slaps our face off.")elif next == "taunt bear" and not bear_moved:print "The bear has moved from the door. you can go through it now."bear_moved = Trueelif next == "open door" and bear_moved:gold_room()else:print "I got no idea what that means."def cthulhu_room():print "Here you see the great evil Cthulhu."print "He, it, whatever stares at you and you go insane."print "Do you flee for your life or eat your head?"next = raw_input("> ")if "flee" in next:start()elif "head" in next:dead("Well that was tasty!")else:cthulhu_room()def dead(why):print why, "Good job!"exit(0)def start():print "You are in a dark room."print "There is a door to your right and left."print "Which one do you take?"next = raw_input("> ")if next == "left":bear_room()elif next == "right":cthulhu_room()else:dead("You stumble around the room until you starve.")start()

加分练习1. 画一个游戏地图，看看你玩的流程。
2. 修改你的错误，包括拼写错误。
3. 为函数写评论，还记得doc文档吗？在函数里面第一行注释，包含在"""中。
4. 扩展你的游戏，你能简洁的扩展它吗？
5. 在gold_room中有一个很不好的方法去判断你输入的是不是数字，你能有更好的方法改进吗？参考int()方法。if nexe.isdigit():
