while 循环
while怎么加进程序里不出错 比如给下面代码加个循环1.1. temp = input("抱歉，您的输入有误，请输入一个整数：")
2. temp = input('请输入一个年份：')
3. while not temp.isdigit():
4.
5. year = int(temp)
6. if year/400 == int(year/400):
7. print(temp + ' 是闰年！')
8. else:
9. if (year/4 == int(year/4)) and (year/100 != int(year/100)):
10. print(temp + ' 是闰年！')
11. else:
12. print(temp + ' 不是闰年！')
