?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

import datetime from dateutil.relativedelta import relativedelta   t=datetime.datetime.now()   #当前日期 d = datetime.date.today() print(d)   # 1天前 d1= d - relativedelta(days=1) print(d1)   #  一个月前 d2=d - relativedelta(months=1) print(d2)   # 1年前 d3=d - relativedelta(years=1) print(d3)     # 1天后 d1=d - relativedelta(days=-1) print(d1)   #  一个月后 d2=d - relativedelta(months=-1) print(d2)   # 1年后 d3=d - relativedelta(years=-1) print(d3)

如果报错需要先安装模块
