import datetime 获得当前时间 now = datetime.datetime.now() ->这是时间数组格式 转换为指定的格式: otherStyleTime = now.strftime("%Y-%m-%d %H:%M:%S") 5.获得三天前的时间 方法: import time import datetime 先获得时间数组格式的日期 threeDayAgo = (datetime.datetime.now() - datetime.timedelta(d...

1 I solved it like this: dtToday= the reference date dtDates= a datetime sequence of the available dates nbOffset= the number of days/months/years we want to go back Code: defprevious_day(dtToday, dtDates, nbOffset): prevx = dtToday - pd.DateOffset(days=nbOffset)returntest_d...
