（重发）优化版甲鱼猜数字游戏~

VIRUS_2091

依旧重发。。。
甲鱼课上讲的猜数字小游戏，但是优化版！

1. import random
   
2. LOWER_BOUND = 1
   
3. UPPER_BOUND = 100
   
4. secret_number = random.randint(LOWER_BOUND, UPPER_BOUND)
   
5. print(f"Now I'm thinking about a number that ranges from {LOWER_BOUND} to {UPPER_BOUND} ")
   
6. print("Guess what it is!")
   
7. 
   
8. def check_guess(guess, secret):
   
9.     if guess < secret:
   
10.         return "Too small! Try a larger one~"
    
11.     elif guess > secret:
    
12.         return "Too large! Try a smaller one~"
    
13.     else:
    
14.         return "Congratulations! You've found out the corresponding number!"
    
15. attempts = 0
    
16. max_attempts = 10
    
17. 
    
18. print(f"You have {max_attempts} chances. Here we start!\n")
    
19. 
    
20. while attempts < max_attempts:
    
21.     try:
    
22.         guess = int(input("Please input your assumption: "))
    
23.     except ValueError:
    
24.         print("Invalid number! Try enter a whole number~")
    
25.         continue
    
26. 
    
27.     attempts += 1
    
28.    
    
29.     result = check_guess(guess, secret_number)
    
30.     print(result)
    
31.    
    
32.     if guess == secret_number:
    
33.         print(f"{attempts} times till you get the answer! Well done! ")
    
34.         break
    
35.    
    
36.     remaining = max_attempts - attempts
    
37.     if remaining > 0:
    
38.         print(f"{remaining} chances remaining~ \n")
    
39.     else:
    
40.         print("Just wasted all your chances! ")
    
41.         print(f"The secret number is {secret_number}. Try again next time~ ")

可以看看相较基础版猜数字的优化点~

FishC

这个优化版确实比基础版强了不少，咱们来一起看看它“优化”在哪里～

• 增加了上下限常量：用LOWER_BOUND和UPPER_BOUND来定义范围，改起来方便，代码也更清晰。
• 把判断逻辑封装成函数check_guess，主逻辑更简洁，也便于复用。
• 限制了猜测次数max_attempts = 10，让游戏更有挑战性，不会无限猜下去。
• 加入了try...except处理输入异常，输字母或小数不会直接报错崩溃，提示用户重新输入。
• 每次猜完都会提示剩余次数，最后还会公布正确答案，用户体验更好。
• 使用了f-string格式化输出，代码更简洁，字符串拼接更直观。
  

所以说，这个版本在代码结构、输入健壮性、游戏体验三个方面都做了优化，已经是一个完整又好玩的小项目啦！
