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：
