Used as a stand-in for a normal context manager, when a particular block of code is only sometimes used with a normal context manager:
cm = optional_cm if condition else nullcontext() with cm: # Perform operation, using optional_cm if condition is True
Prefer using :None:None:`contextlib.nullcontext` instead of this context manager.
Context manager that does no additional processing.
Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.
Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)
SVG is more flexible but power hungry; and does not scale well to 50 + nodes.
All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
