Matt C. Wilson updated TINKERPOP-3119:
--------------------------------------
Description:
The gremlin_python `Element` class (and thus all Graph object subclasses) has a
`properties` property that must be iterated and each member inspected to find a
particular property by name.
[https://github.com/apache/tinkerpop/blob/8aad0bc72a1d11791ddbd5070962caa23223bf3d/gremlin-python/src/main/python/gremlin_python/structure/graph.py#L29-L39|https://github.com/apache/tinkerpop/blob/master/gremlin-python/src/main/python/gremlin_python/structure/graph.py]
Example:
{{```}}
{{for vp in vertex.properties:}}
{{ if vp.key == key:}}
{{ logging.debug(f"\{vertex}.properties['\\{key}']: \{vp.value}")}}
{{ return vp.value}}
{{```}}
{{It would be nice to be able to do:}}
{{```}}
{{p = vertex.properties}}
{{return vertex[key] if p and p.hasattr(key) else None}}
{{```}}
