swmm.pandas.Output.subcatch_result¶

Output.subcatch_result(subcatchment, time, asframe=True)[source]¶

For a subcatchment at one or more given times, get all attributes.

Only one of subcatchment or time can be multiple (eg. a list), not both.

Parameters

subcatchment: Union[int, str, Sequence[Union[int, str]], None],

The subcatchment(s) name(s) or index(s).

time: Union[int, str, Sequence[Union[int, str]], None],

THe datetime(s) or simulation index(s).

asframe: bool

A switch to return an indexed DataFrame. Set to False to get an array of values only, defaults to True.

Returns

Union[pd.DataFrame,np.ndarray]

A DataFrame or ndarray of all attribute values subcatchment(s) at given time(s).

Examples

Pull all attributes at start, middle, and end time steps for a single catchment

>>> from swmm.pandas import Output,test_out_path
>>> out = Output(test_out_path)
>>> out.subcatch_result("SUB1",[0,out.period/2,out.period-1])

Pull all attributes for all catchments at the start of the simulation

>>> out = Output(test_out_path)
>>> out.subcatch_result(out.subcatchments,'1900-01-01')
