Python 判断闰年并计算年份天数

def g(n):
    if n % 4 == 0 and n % 100 != 0 or n % 400 == 0:
        return True
    else:
        return False

year = int(input('请输入年份:'))
while year <= 0:
    year = int(input('请输入年份:'))

if g(year):
    print('{}年有366天'.format(year))
else:
    print('{}年有365天'.format(year))
