Calculates length of cul-de-sacs for subgraph around each node if radius is set, or for
whole graph, if radius=None.
Subgraph is generated around each node within set radius. If distance=None,
radius will define topological distance, otherwise it uses values in distance
Graph representing street network.
Ideally generated from GeoDataFrame using momepy.gdf_to_nx()
Include all neighbors of distance <= radius from n
if 'sum', calculate total length, if 'mean' calculate mean length
calculated attribute name
name of attribute of node degree (momepy.node_degree())
name of attribute of segment length (geographical)
Use specified edge data key as distance.
For example, setting distance=’weight’ will use the edge weight to
measure the distance from the node n.
if True, shows progress bars in loops and indication of steps
