为什么显示TypeError: not all arguments converted during strin...

year = input('请输入一个年份：')

while not year.isdigit():
    year = input("抱歉，您的输入有误，请输入一个整数：")
int(year)
if year%400==0:
    print("是闰年")
else:
    if year%4==0 and year%100!=0:
      print("是闰年")
    else:
      print("不是闰年")

while not year.isdigit():这里只是检测是不是全是数字
int(year)这里转换为整型却没有赋值，没办法使用，year还是一个字符串https://cdn.jsdelivr.net/gh/master-of-forums/master-of-forums/public/images/patch.gif
