[已解决]求助：猜数字小游戏增加报错功能

EggZZ

刚刚开始学python，纠结while和if循环纠结了好久也没想出来，请大佬们帮忙修改一下， 感谢！问题1：应该在哪里添加 isinstance()
           我尝试过在while循环下加，但是因为guess变量已经设定为int()了，程序直接就报错了
问题2：我自己增加了一个条件：如果猜的数字大于10，则显示数字过大，但是显得整个代码很乱，又不知道该从哪里开始简化，求解答！
感谢大佬们赐教
第一次发帖，不知道缩进改的对不对，所以也贴了张代码的截屏

1. from random import randint
   
2. num = randint(1, 10)
   
3. guess = int(input("Enter a number:\n"))
   
4. guess_count = 0
   
5. guess_limit = 5
   
6. out_of_guess = False
   
7. 
   
8. while guess != num and not out_of_guess:
   
9.     guess_count += 1
   
10.     if guess_count < guess_limit:
    
11.         if num < guess <= 10:
    
12.             guess = int(input("Too Big!\n"))
    
13.         elif guess < num <= 10:
    
14.             guess = int(input("Too Small!\n"))
    
15.         else:
    
16.             guess = int(input("Number should not bigger than 10!\n"))
    
17.     else:
    
18.         out_of_guess = True
    
19.     if out_of_guess:
    
20.         print("Out of Guesses!")
    
21.         break
    
22. else:
    
23.     print("Bingo!")

没必要用isinstance，直接isdiigit就好了.

1. from random import randint
   
2. num = randint(1, 10)
   
3. guess = input("Enter a number:\n")
   
4. while not guess.isdigit():
   
5.     guess = input("Enter a number:\n")
   
6. guess = int(guess)
   
7. guess_count = 0
   
8. guess_limit = 5
   
9. out_of_guess = False
   
10. 
    
11. while guess != num:
    
12.     guess_count += 1
    
13.     if guess_count < guess_limit:
    
14.         if num < guess <= 10:
    
15.             guess = int(input("Too Big!\n"))
    
16.         elif guess < num <= 10:
    
17.             guess = int(input("Too Small!\n"))
    
18.         else:
    
19.             guess = int(input("Number should not bigger than 10!\n"))
    
20.     else:
    
21.         print("Out of Guesses!")
    
22.         break
    
23. else:
    
24.     print("Bingo!")

感谢感谢， 然后 out_of_guess 这个条件其实是没必要的是吗？

没必要，而且还要加一个判断，看着更麻烦。
