我如何才能将 pandas 时间戳记抵消一定数量的月数? [英] How can I get pandas Timestamp offset by certain amount of months?

问题描述

假设我有一个熊猫Timestamp对象t1.

Suppose I have a pandas Timestamp object t1.

import pandas a pd
t1=pd.Timestamp('2013-04-01 00:00:00')

如何获得另一个熊猫时间戳，从t1开始偏移k个月?

How can I get another pandas timestamp, offset by k months from t1?

推荐答案

您可以使用

You can use relativedelta:

In [135]:
k=2
t1 + pd.datetools.relativedelta(months=k)

Out[135]:
Timestamp('2013-06-01 00:00:00')

或 DateOffset :

In [136]:
k=2
t1 + pd.DateOffset(months=k)

Out[136]:
Timestamp('2013-06-01 00:00:00')

感谢@AlexRiley的建议修改，relativedelta已移至

Thanks to @AlexRiley for the suggested edit, relativedelta has been moved to

pd.offsets.relativedelta自0.20.0
