一开始只通过50%的数据，一直找错误，发现逻辑没问题，但就是只过50%，代码如下：

class Data:
    def __init__(self,year,month,day):
        self.year = year
        self.month = month
        self.day = day

record = [0,31,28,31,30,31,30,31,31,30,31,30,31]

def main():
    while True:
        try:
            year,month,day = map(int,(input().split(" ")))
            if year<0:
                print("Input error!")
                return 0
            if month>12 or month<1:
                print("Input error!")
                return 0
            if year%400==0 or (year%4==0 and year%100!=0):
                record[2] = 29
            if day>record[month] or day<1:
                print("Input error!")
                return 0
            he = 0
            for i in range(1,month):
                he = he+record[i]
            print(he+day)
        except:
            break
if __name__ == '__main__':
    main()

后来发现是多组输入的问题，我这里有return 0 ，有些多组输入就不支持了，好坑人，把return 0全部改成...
