Returns whether a list of degrees can be a degree sequence of some graph, with or without multiple and loop edges, depending on the allowed edge types in the remaining arguments.
|out_deg||the list of degrees. For directed graphs, this list must contain the out-degrees of the vertices.|
|in_deg||the list of in-degrees for directed graphs. This parameter must be None for undirected graphs.|
|loops||whether loop edges are allowed.|
|multiple||whether multiple edges are allowed.|
|True if there exists some graph that can realize the given degree sequence with the given edge types, False otherwise.|
