[python]猜数小游戏

python新手，老手请忽视。

最近开始学习python，正在适应python中，这是第一次用python写简单的小算法，呵呵。

#!/usr/bin/python
import random
import time

while True:
	num = random.randint(1,100)
	guess = int(raw_input("guess a number:"))
	begin = time.time()
	
	while guess != num:
		if guess < num:
			print "please input a bigger num:"
		else:
			print "please input a smaller num:"
		guess = int(raw_input("guess again:"))

	finish = time.time()
	total = finish-begin
	print "total used time %f" % total
	
	if total < 5:
		print "impossible!"
	elif total < 10:
		print "genius!"
	elif total < 15:
		print "clever!"
	elif total < 30:
		print "normal level!"
	elif total < 45:
		print "poor!"
	else:
		print "stupid!"
	
	print "the number you guessed is %d" % num
	again = raw_input("do you wanna play again?(\'y\' or \'n\')");
	if again != 'y':
		break;
