swmm.pandas.Output.link_result¶

Output.link_result(link, time, asframe=True)[source]¶

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

Only one of link or time can be multiple.

Parameters

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

The link(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 link(s) at given time(s).

Examples

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