import sys



def is_leap_year(year):
    return (year % 400 == 0) or (year % 4 == 0 and year % 100 != 0) 

def day_of_month(year,month,day):
    day_in_month = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31]
    if is_leap_year(year):
        day_in_month[1] = 29

    return sum(day_in_month[:month - 1])+day

for line in sys.stdin:
    if line.strip() == "":
        break
    else:
        x = line.strip()
        year,month,day = [int(i) for i in x.split()]

print(day_of_month(year,month,day))

利用sys.stdin控制输入流，for line in sys.stdin: 若line.strip()为空则break，若不为空，分割装入列表并且赋值
