(Py练习)输入某年某月判断天数

# 输入某年某月，判断这一天是这一年的第几天

year = int(input("year:\n"))

month = int(input("month:\n"))

day = int(input("day:\n"))

months = (0, 31, 59, 90, 120, 151, 181, 212, 243, 273, 304, 334)

if 0 < month <= 12:

    sum = months[month - 1]

else:

    print('Date Error\n')

sum += day

leap = 0

# 判断是否为闰年

# 判断标准是：1、能被4整除且不能整除100；2、能整除400

# and 优先级高于 or

if (year % 400 == 0) or (year % 4 == 0) and (year % 100 != 0):

    leap = 1

if (leap == 1) and (month > 2):

    sum += 1

print(f'it is rhe the %dth day.' % sum)
