It allows you to check whether an integer value is not in a collection of values: Python >>> 5 not in [2, 3, 5, 9, 7] False >>> 8 not in [2, 3, 5, 9, 7] True In the first example, you get False because 5 is in the target list. In the second example, you get...
complement(G) - graph complement create_empty_copy(G) - return an empty copy of the same graph class convert_to_undirected(G) - return an undirected representation of G convert_to_directed(G) - return a directed representation of G
