import random
time = 3
secret=random.randint(1,10)
print('-----------课后练习4-----------')
guess = 0
print('猜一下今天的幸运数字是多少:',end='')
while (guess != secret) and (times > 0):
    temp = input()
    guess = int(temp)
    times = times - 1
    if guess == secret:
        print('你真聪明')
        print('可惜你猜中我 也不会给你奖励')
    else:
        if guess >secret:
            print('哼，不按要求来')
        else:
            print('再试一次，再试一次')
        if times > 0:
            print('再给最后一次机会:', end = '55')
        else:
            print('机会用完啦')
