python实践项目四：猜数字游戏

题目要求：在1-20中随机生成一个数字，你来猜，只有6次机会。

举例一：

 #!/usr/bin/python
 # -*- coding: UTF-8 -*-

 import random
 secretNumber=random.randint(1,20)
 print "I'm thinking of a number between 1 and 20."
 times = 0
 for i in range(1,7):
     print "Take a guess:"
     guess=int(input())
     if guess<secretNumber:
         print "Your guess is too low."
         times+=1
     elif guess>secretNumber:
         print "Your guess is too high."
         times += 1
     else:
         times += 1
         break
 if guess==secretNumber:
     print "You are right! The number is:%d,you spend %d times" %(secretNumber,times)
 else:
     print "You are wrong,and the number is:%d" %secretNumber

运行结果：

举例二：

 #!/usr/bin/python
 # -*- coding: UTF-8 -*-
 import random
 def guessNumber():
     num=random.randint(1,20)
     print "提前展示该随机数字：",num #方便测试可以先打印出该随机数字
     guess=int(raw_input("我想了一个1-20的数字，给你6次机会你来猜。请猜一个数字：\n"))
     times=0
     while times<5:
         if num==guess:
             print "你猜对了！你花了%d次！" %(times+1)
             break
         if num > guess:
             guess = int(raw_input("小了！请再猜："))
             times+=1
         if num < guess:
             guess = int(raw_input("大了！请再猜："))
             times+=1
     if times==5:
         print "6次机会用完了都没猜对！"

 guessNumber()

运行结果：
