猜测程序

while

import random
answer = random.randint(1,10)
guess_limit = 3#最大猜测次数
guess_count = 0#当前猜测次数
while(guess_count < guess_limit):
    guess = eval(input('1-10之间数字，猜猜？'))
    if(answer == guess):
         print('guess Right!')
         print('game over! 88')
         break;
    elif(guess > answer):
         print('Too Big!',end='')
    else:
         print('Too Small!',end='')
    guess_count += 1
    if(guess_limit == guess_count):
        print('你已经用完猜测次数：' + str(guess_limit))
        print('You Have Failed!')
        break
    else:
        print('Guess Please!')

第一阶段代码

#支持输入猜测次数
#支持时间记录             used_time = end_time - start_time
#支持多轮游戏                 while if break
#tuple 元组 记录每局数据    .append((cycle,is_right,used_time))
#三元运算替代             label = 'WIN' if(_is_right) else 'FAIL'
#lambda                 best_score = min(score,key=lambda x:x[2])
