select_observations¶

select_observations(df: pandas.core.frame.DataFrame, timestamps: pandas.core.series.Series, freq: str, start: Optional[Union[str, pandas._libs.tslibs.timestamps.Timestamp]] = None, end: Optional[Union[str, pandas._libs.tslibs.timestamps.Timestamp]] = None, periods: Optional[int] = None) → pandas.core.frame.DataFrame[source]¶

Select observations from dataframe with known timeline.

Parameters

df (pandas.core.frame.DataFrame) – dataframe with known timeline
timestamps (pandas.core.series.Series) – series of timestamps to select
freq (str) – pandas frequency string
start (Optional[Union[str, pandas._libs.tslibs.timestamps.Timestamp]]) – start of the timeline
end (Optional[Union[str, pandas._libs.tslibs.timestamps.Timestamp]]) – end of the timeline
periods (Optional[int]) – number of periods in the timeline

Returns

dataframe with selected observations

Return type

pandas.core.frame.DataFrame
