想写能持续输入分数的程序，但当打印是‘输入错误’时，程序就停止了，求支招！

secret = int(input('输入分数：'))
while 0 <= secret <=100:
     if  90 <= secret <=100:
        print('A')
     elif 80 <=secret <90:
        print('B')
   
     elif 70 <=secret <80:
        print('C')
   
     elif 0 <=secret <70:
        print('D')
     secret = int(input('输入分数：'))
else:
    print('输入错误')
    secret = int(input('输入分数：'))     
     

慎为

count = 5
while count > 0:
    secret = int(input('输入分数：'))
    count -= 1
    if 90<= secret <= 100:
        print('A')
    elif 80<= secret < 90:
        print('B')
    elif 70 <= secret < 80:
        print('C')
    elif 60<= secret < 70:
        print('D')
    elif secret < 60:
        print('E')
    elif secret > 100:
        print('输入错误')
