python判断年份是否是闰年

群里有小伙伴找这个，就弄了下。

#!/usr/bin/python3
# -*- coding: utf-8 -*-
while True:
    try:
        year = int(input("输入年份："))
        if year%4 == 0 and year%100 !=0 or year%400 == 0:
            print("{}闰年".format(year))
            continue
        else:
            print("{}非闰年".format(year))
            continue
    except Exception as e:
        print("输入字符非整数，请输入正确数字！")
        continue
