def which_day(year,month,day):    list=[31,28,31,30,31,30,31,31,30,31,30,31]    which_day=0    if (year%4==0)and(year%4!=0) or (year %400=0):        list [1]=29        for i in range (1,month):            if month ==1;            print day            which_day=which_day+list[i-1]        which_day=which_day+day        print which_dayif __name__=="__ main__":    year =int (input ("请输入年份："))    month = int(input ("请输入月份："))    day= int(input ("请输入天："))    which_day(year,month,day)
