python - 如何在python中将天转换为年和月？

Question

如何在python中将天转换为年、月和日？
例如:如果某人是 5,538 天大。我怎样才能通过这样的年月日来显示它:15 岁 2 个月零 1 天
这是为了获取用户的输入

print "Please enter your birthday"
bd_year = int(raw_input("Year: "))
bd_month = int(raw_input("Month: "))
bd_day = int(raw_input("Day: "))

from datetime import date
now = date.today()

birthdate = date(int(bd_year), int(bd_month), int(bd_day))
age_in_days = now - birthdate

print "Your age is %s" % age_in_days

现在我需要以年月日为单位计算此人的生日

如何使用dateutil.relativedelta.relativedelta来自 dateutil library ?例如:

from dateutil.relativedelta import relativedelta
rdelta = relativedelta(now, birthdate)
print 'Age in years - ', rdelta.years
print 'Age in months - ', rdelta.months
print 'Age in days - ', rdelta.days
