Method size

easygraph/classes/graph.py:446–476

Returns the number of edges or total of all edge weights. Parameters ----------- weight : String or None, optional The weight key. If None, it will calculate the number of edges, instead of total of all edge weights. Returns -------

(self, weight=None)

        Parameters
        -----------
        weight : String or None, optional
            The weight key. If None, it will calculate the number of
            edges, instead of total of all edge weights.

        Returns
        -------
        size : int or float, optional (default: None)
            The number of edges or total of all edge weights.

        Examples
        --------

        Returns the number of edges in G:

        >>> G.size()

        Returns the total of all edge weights in G:

        >>> G.size(weight='weight')
