python 获取未来指定天数的日期

from datetime import timedelta, date

def get_day_of_day(n=0):
    '''''
    if n>=0,date is larger than today
    if n<0,date is less than today
    date format = "YYYY-MM-DD"
    '''
    if(n<0):
        n = abs(n)
        return date.today()-timedelta(days=n)
    else:
        return date.today()+timedelta(days=n)
#获取未来三天的日期
print(get_day_of_day(1))
print(get_day_of_day(2))
print(get_day_of_day(3))

运行效果如图：
