Edge Types Dictionary

s3dgraphy.edges.edge.EDGE_TYPES

dict() -> new empty dictionary dict(mapping) -> new dictionary initialized from a mapping object’s

(key, value) pairs

dict(iterable) -> new dictionary initialized as if via:

d = {} for k, v in iterable:

d[k] = v

dict(**kwargs) -> new dictionary initialized with the name=value pairs

in the keyword argument list. For example: dict(one=1, two=2)

The EDGE_TYPES dictionary contains all valid edge types with their labels and descriptions.
