Parameters :

data : boolean, optional (default=False)

If False return a list of nodes. If True return a two-tuple of node and node data dictionary

Returns :

nlist : list

A list of nodes. If data=True a list of two-tuples containing (node, node data dictionary).

Examples

>>> G = nx.Graph()   # or DiGraph, MultiGraph, MultiDiGraph, etc
>>> G.add_path([0,1,2])
>>> G.nodes()
[0, 1, 2]
>>> G.add_node(1, time='5pm')
>>> G.nodes(data=True)
[(0, {}), (1, {'time': '5pm'}), (2, {})]
