在Python中，如果用戶輸入的值不正確，我如何使輸入驗證保持循環

Question

如果用戶輸入的數字低於下面的值，如何使我的代碼循環回到輸入（並再次檢查值） 0或高於100或沒有輸入整數

NameList = [] 
Name1List = [] 
def Va(): 
    while True: 
     try: 
      int(NameMSplit[1]) 
      if int(NameMSplit[1]) > 0 and int(NameMSplit[1]) < 100: 
       return NameMSplit[1] 
      else: 
       print ("Number is not between 0 and 100") 
     except ValueError: 
      print("Please make sure it's a number ") 

#Main Code 
NameMarks = input("Please input your name followed by your marks seperated by spaces ") 
NameMSplit = NameMarks.split() 
V = Va() 
while NameMarks != 'Q': 
    Name =(NameMSplit[0]) 
    Name1 = (NameMSplit[1]) 
    NameList.append(Name) 
    Name1List.append(Name1) 
    NameMarks = input("Please input your name followed by your marks seperated by spaces ") 
    NameMSplit = NameMarks.split() 
print (Name1List, NameList)

您可以在您的函數的輸入如下：

def Va(): 
    while True: 
     NameMarks = input("Please input your name followed by your marks seperated by spaces ") 
     NameMSplit = NameMarks.split() 
     try: 
      int(NameMSplit[1]) 
      if int(NameMSplit[1]) > 0 and int(NameMSplit[1]) < 100: 
       return NameMarks 
      else: 
       print ("Number is not between 0 and 100") 
     except ValueError: 
      print("Please make sure it's a number ") 

#Main Code 
NameMarks = Va() 
...
