【大学生Python】判断平闰年和各月份的天数

判断平闰年：

year = int(input('请输入年份：'))

if (year % 4 == 0 and year % 100 != 0) or year % 400 == 0:
    print(f'{year}年是闰年。')
else:
    print(f'{year}年是平年。')

判断平闰年各月份的天数：

year = int(input('请输入年份：'))
month = int(input('请输入月份：'))

if month in [1, 3, 5, 7, 8, 10, 12]:
    print(f'{year}年{month}月有31天')
elif month in [4, 6, 9, 11]:
    print(f'{year}年{month}月有30天')
elif month == 2:
    if (year % 4 == 0 and year % 100 != 0) or year % 400 == 0:
        print(f'{year}年{month}月有29天')
    else:
        print(f'{year}年{month}月有28天')
else:
    print('输入有误，请输入有效数据！')
