建议ex27-31连起来学习

迄今为止，我们学会输出字符串和函数，这些基础足够让我们的代码从头开始运行，到尾部结束。现在我们有了if,else和elif，像上一节练习，我们可以开始让脚本做决策了。

注意，使用了 if 的嵌套，另外，脚本内容有点儿童不宜。。。

print("""You enter a dark room with two doors.
Do you go though door #1 or door #2?""")door = input('>')if door == "1":print("There's a giant bear here eating a cheese cake.")print("What do you do?")print("1. Take the cake.")print("2. Scream at the bear.")bear = input(">")if bear == "1":print("The bear eats your face off. Good job!")elif bear == '2':print("The bear eats your legs off. Good job!")else:print(f"Well, doing {bear} is probably better.")print("Bear runs away.")elif door == "2":print("You stare into the endless abyss at Cthulhu's retina.")print("1. Blueberries.")print("2. Yellow jacket clothespins.")print("3. Understanding revolvers yelling melodies.")insanity = input('>')if insanity == '1' or insanity == '2':print("Your body survives powered by a mind of jello.")print("Good job!")else:print("The insanity rots your eyes into a pool of muck.")print("Good job!")else:print("You stumble around and fall on a knife and die. Good job!")

What you should see

You enter a dark room with two doors.
Do you go though door #1 or door #2?
>1
There's a giant bear here eating a cheese cake.
What do you do?
1. Take the cake.
2. Scream at the bear.
>2
The bear eats your legs off. Good job!
