Unexpected output to STDOUT when iterating over iterable returned by graph_from_networkx

Thank you so much for your work on this library. I'm a graduate student just getting into this technique, and your framework and documentation has been quite helpful! 🙇‍♂️👏

I'm doing a project involving callgraphs of Android malware (~40k vertices), which are currently in gml format. I've been converting them into grakel graphs by way of networkx, as below:

gml_paths = [os.path.join(root, file) for root, directories, files in os.walk(path) for file in files if file.endswith(".gml")]
networkx_graphs = [nx.read_gml(path) for path in gml_paths]
grakel_graphs = graph_from_networkx(networkx_graphs, as_Graph=True)

The thing that is surprising to me is that the second I use grakel_graphs, for example, be coercing into a list list(grakel_graphs), a string representation of the graph gets dumped to STDOUT.

When I work in Jupyter Notebook, this results in the following error:

Is this a logging feature or is there some way to disable this functionality to silently convert to lists?

Apologies in advance if there is a naive Python issue on my end. I'm an experienced developer, but new to the language ecosystem.

Thanks!
