How can I get pandas Timestamp offset by certain amount of months?
提问by Apogentus
Suppose I have a pandas Timestamp object t1.
假设我有一个Pandas时间戳对象 t1。
import pandas a pd
t1=pd.Timestamp('2013-04-01 00:00:00')
How can I get another pandas timestamp, offset by k months from t1?
我怎样才能得到另一个Pandas时间戳，从 t1 偏移 k 个月？
回答by EdChum
You can use relativedelta:
您可以使用relativedelta：
In [135]:
k=2
t1 + pd.datetools.relativedelta(months=k)
Out[135]:
Timestamp('2013-06-01 00:00:00')
Or DateOffset:
In [136]:
k=2
t1 + pd.DateOffset(months=k)
Out[136]:
Timestamp('2013-06-01 00:00:00')
Thanks to @AlexRiley for the suggested edit, relativedeltahas been moved to
感谢@AlexRiley 的建议编辑，relativedelta已移至
pd.offsets.relativedeltasince 0.20.0
pd.offsets.relativedelta自从 0.20.0
