1 2	`from dateutil.relativedelta import relativedelta` `diff = relativedelta(today, my_birthday)`

通过输出可以发现，我们能获取到两个日期中间相差几年，几个月和几天

1	`relativedelta(years=+26, months=+8, days=+17)`

print(diff.years)
print(diff.months)
print(diff.days)

26
8
17

获取日期列表，如果需要获取连续五周周二的日期，通过dateutil可以很容易实现

1 2	`from dateutil.rrule import rrule, WEEKLY` `pp(list(rrule(WEEKLY,` `count=10, dtstart=next_tuesday)))`

输出为

[datetime.datetime(2018, 12, 4, 8, 59, 6),
 datetime.datetime(2018, 12, 11, 8, 59, 6),
 datetime.datetime(2018, 12, 18, 8, 59, 6),
 datetime.datetime(2018, 12, 25, 8, 59, 6),
 datetime.datetime(2019, 1, 1, 8, 59, 6),
 datetime.datetime(2019, 1, 8, 8, 59, 6),
 datetime.datetime(2019, 1, 15, 8, 59, 6),
 datetime.datetime(2019, 1, 22, 8, 59, 6),
 datetime.datetime(2019, 1, 29, 8, 59, 6),
 datetime.datetime(2019, 2, 5, 8, 59, 6)]
