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
