问题描述
我希望将以下<'pandas.tseries.resample.DatetimeIndexResampler'>
类型对象转换为大熊猫DataFrame对象(< ;'pandas.core.frame.DataFrame'>
)。然而,我在大熊猫文档中找不到相关的功能,让我这样做。
I wish to convert the following <'pandas.tseries.resample.DatetimeIndexResampler'>
type object into a pandas DataFrame object (<'pandas.core.frame.DataFrame'>
). However I cannot find the relevant function in the pandas documentation to allow me to do this.
数据采用以下格式:
M30
Date
2016-02-29 -61.187699
2016-03-31 -60.869565
2016-04-30 -61.717922
2016-05-31 -61.823966
2016-06-30 -62.142100
...
任何人都可以提供替代解决方案?
Can anyone provide an alternative solution?
推荐答案
您需要一些总体功能,如 sum
或意味着
。
You need some aggregate function like sum
or mean
.
您的数据示例:
print (df)
M30
Date
2016-02-29 -61.187699
2016-03-31 -60.869565
2016-04-30 -61.717922
2016-05-31 -61.823966
2016-06-30 -62.142100
#resample by 2 months
r = df.resample('2M')
print (r)
DatetimeIndexResampler [freq=<2 * MonthEnds>,
axis=0,
closed=right,
label=right,
convention=start,
base=0]
#aggregate sum
print (r.sum())
M30
Date
2016-02-29 -61.187699
2016-04-30 -122.587487
2016-06-30 -123.966066
#aggregate mean
print (r.mean())
M30
Date
2016-02-29 -61.187699
2016-04-30 -61.293743
2016-06-30 -61.983033
#aggregate first
print (r.first())
M30
Date
2016-02-29 -61.187699
2016-04-30 -60.869565
2016-06-30 -61.823966
