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！
import random
secret = random.randint(1,99)
guess = 0
tries = 0
print "AHOY! I'm the Dread Pirate Roberts,and I have a secret!"
print "It is a number from 1 to 99. I'll give you 6 tries."
while guess != secret and tries < 6:
guess = input("What's yer guess?")
if guess < secret:
print "Too low ,ye scurvy dog!"
elif guess > secret:
print "Too high,landlubber!" tries = tries + 1 if guess == secret:
print "Avast! ye got it! Found my secret, ye did!"
else:
print "No more guesses! Better luck next time, matey!"
print "The secret number was",secret
这是运行效果(猜对了)：
>>> ================================ RESTART ================================
>>>
AHOY! I'm the Dread Pirate Roberts,and I have a secret!
It is a number from 1 to 99. I'll give you 6 tries.
What's yer guess?50
Too low ,ye scurvy dog!
What's yer guess?75
Too low ,ye scurvy dog!
What's yer guess?87
Too high,landlubber!
What's yer guess?81
Avast! ye got it! Found my secret, ye did!
(猜错了)
>>> ================================ RESTART ================================
>>>
AHOY! I'm the Dread Pirate Roberts,and I have a secret!
It is a number from 1 to 99. I'll give you 6 tries.
What's yer guess?1
Too low ,ye scurvy dog!
What's yer guess?2
Too low ,ye scurvy dog!
What's yer guess?3
Too low ,ye scurvy dog!
What's yer guess?4
Too low ,ye scurvy dog!
What's yer guess?5
Too low ,ye scurvy dog!
What's yer guess?6
Too low ,ye scurvy dog!
No more guesses! Better luck next time, matey!
The secret number was 24
令我惊讶的是这一句：
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！
