s.isdigit()使用问题

lugiasong

新手自己看视频写的，请问:
1.在这基础上如何使用s.isdigit() 来提示输出类型错误并要求重新输入
2.整个过程是否有更简便的写法
谢谢
import random
times = 3
x = random.randint(1,10)
print("A Small Game")
temp=input("Please guess which integer in my mind: ")
guess = int(temp)
if guess == x:
  print("Woa, how do you know my mind!")
  print("but i have no gift for you~")
else :
  while (guess != x) and (times > 0):   
    if guess > x:
      print("what a pity, it's too big.")
    else:
      print("what a pity, it's too small.")
    temp = input("Please guess it again:")
    guess = int(temp)
    times = times - 1
    if times == 0:
      print("Sorry,you have no chance")
    if guess == x:
      print("Woa, how do you know my mind!")
      print("but i have no gift for you~")
print("Game Over.")
from time import sleep
sleep(15)

现有代码，如果输入非数字肯定会报错。

1. import random
   
2. from time import sleep
   
3. 
   
4. def getint(msg):
   
5.     s=input(msg)            
   
6.     while not s.isdigit():
   
7.         s=input('请输入数字：')
   
8.     return int(s)   
   
9. 
   
10. times = 3
    
11. x = random.randint(1,10)
    
12. print("A Small Game")
    
13. guess=getint("Please guess which integer in my mind: ")
    
14. if guess == x:
    
15.   print("Woa, how do you know my mind!")
    
16.   print("but i have no gift for you~")
    
17. else :
    
18.   while (guess != x) and (times > 0):   
    
19.     if guess > x:
    
20.       print("what a pity, it's too big.")
    
21.     else:
    
22.       print("what a pity, it's too small.")
    
23.     guess = getint("Please guess it again:")
    
24.     times = times - 1
    
25.     if times == 0:
    
26.       print("Sorry,you have no chance")
    
27.     if guess == x:
    
28.       print("Woa, how do you know my mind!")
    
29.       print("but i have no gift for you~")
    
30. print("Game Over.")

谢谢你的回复
我才看到入门的第五课
下面的这部分我还没学到
def getint(msg):
    s=input(msg)            
    while not s.isdigit():
        s=input('请输入数字：')
    return int(s)
