下边是一个猜数字的小游戏：

几乎所有语言都这样做的……

here we go！

复制代码
 1 import random
 2 secret = random.randint(1,99)
 3 guess = 0
 4 tries = 0
 5 print "AHOY! I'm the Dread Pirate Roberts,and I have a secret!"
 6 print "It is a number from 1 to 99. I'll give you 6 tries."
 7 while guess != secret and tries < 6:
 8     guess = input("What's yer guess?")
 9     if guess < secret:
10         print "Too low ,ye scurvy dog!"
11     elif guess > secret:
12         print "Too high,landlubber!"
13 
14     tries = tries + 1
15 
16 if guess == secret:
17     print "Avast! ye got it! Found my secret, ye did!"
18 else:
19     print "No more guesses! Better luck next time, matey!"
20     print "The secret number was",secret
复制代码

这是运行效果(猜对了)：

The secret number was 24

　　

令我惊讶的是这一句：

?
1
print "The secret number was",secret

　　怎么直接就能显示值得呢？感觉异常的怪！

还有一个，语句后边没有分号，if elif else while 后边要加冒号。

My God !!! 

print secret,guess,tries

这样子居然都行。OK第二个程序运行完毕！
