class Edge:

Class representing a single edge in a graph.

The edge is referenced by its index, so if the underlying graph changes, the semantics of the edge object might change as well (if the edge indices are altered in the original graph).

The attributes of the edge can be accessed by using the edge as a hash:

>>> e["weight"] = 2                  #doctest: +SKIP
>>> print(e["weight"])               #doctest: +SKIP
2

Method	`attributes`	Returns a dict of attribute names and values for the edge
Method	`attribute_names`	Returns the list of edge attribute names
Method	`update_attributes`	Updates the attributes of the edge from dict/iterable E and F.
Method	`count_multiple`	Proxy method to `Graph.count_multiple()`
Method	`delete`	Proxy method to `Graph.delete_edges()`
Method	`is_loop`	Proxy method to `Graph.is_loop()`
Method	`is_multiple`	Proxy method to `Graph.is_multiple()`
Method	`is_mutual`	Proxy method to `Graph.is_mutual()`

def attributes():

Returns a dict of attribute names and values for the edge

def attribute_names():

Returns the list of edge attribute names

def update_attributes(E, **F):

Updates the attributes of the edge from dict/iterable E and F.

If E has a keys() method, it does: for k in E: self[k] = E[k]. If E lacks a keys() method, it does: for (k, v) in E: self[k] = v. In either case, this is followed by: for k in F: self[k] = F[k].

This method thus behaves similarly to the update() method of Python dictionaries.

def count_multiple (INVALID):

Proxy method to Graph.count_multiple()

This method calls the count_multiple method of the Graph class with this edge as the first argument, and returns the result.

See Also Graph.count_multiple() for details.

def delete (INVALID):

Proxy method to Graph.delete_edges()

This method calls the delete_edges method of the Graph class with this edge as the first argument, and returns the result.

See Also Graph.delete_edges() for details.

def is_loop (INVALID):

Proxy method to Graph.is_loop()

This method calls the is_loop method of the Graph class with this edge as the first argument, and returns the result.
