Python问题：至今的年份和年份？

我有一个年份值和一年中的某天，并想转换为日期（天/月/年）。

提前致谢。 :)

datetime.datetime(year, 1, 1) + datetime.timedelta(days - 1)

>>> import datetime

>>> datetime.datetime.strptime(' 120', '%Y %j')

datetime.datetime(, 4, 30, 0, 0)

>>> _.strftime('%d/%m/%Y')

'30/04/'

可以使用date类的date和date函数：

from datetime import date

date.fromordinal(date(year, 1, 1).toordinal() + days - 1)

>>>import datetime

>>>year = int(input())

>>>month = int(input())

>>>day = int(input())

data = datetime.datetime(year,month,day)

daynew = data.toordinal()

yearstart = datetime.datetime(year,1,1)

day_yearstart = yearstart.toordinal()

print ((daynew-day_yearstart)+1)
