https://ask.sagemath.org/question/36938/mixed-graph/?answer=36939#post-id-36939I am not sure about your motivation, but a possibility is to use oriented graphs, and put edges from both `a` to `b` and `b` to `a` when you want to consider `(a,b)` as a non-oriented edge. This double-edge construction is classical to define non-oriented graphs.

https://ask.sagemath.org/question/36938/mixed-graph/?comment=36941#post-id-36941Yes I know that. But I need the diagrams as mixed graph. I need for several purposes. For example I need to print a mixed graph(with some edges without orientation), want its latex commands. Of course I need some operations on mixed graphs, that I had already done using the method you have mentioned.Tue, 14 Mar 2017 09:08:11 +0100https://ask.sagemath.org/question/36938/mixed-graph/?comment=36941#post-id-36941
