年份天数

题目

输入某年某月某日，判断这一天是这一年的第几天？

特殊情况，闰年时需考虑二月多加一天

解答

year = int(input("input year: "))
month = int(input("input month: "))
day = int(input("input day: "))
monthDays = [0, 31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30]


def solution4(y, m, d):
    if y % 4 == 0:
        monthDays[2] = 29
    index = 0
    for m in range(m):
        index += monthDays[m]
    index += d
    return index


print(solution4(year, month, day))
