-------------------------------------
Hi [~mcw], thanks for opening this request. I can see it being convenient with
materialized properties in 3.7. I’m just wondering if that’s the use case you
are referring to with vertex[key]? As opposed to getting the property using
values(), or from a map using valueMap() via a traversal.
In any case, you are welcome to implement this feature if you have the idea for
it, and we’ll be happy to review any PRs.

> Project: TinkerPop
> Issue Type: Bug
> Components: python
> Affects Versions: 3.7.3
> Reporter: Matt C. Wilson
> Priority: Minor
>
> 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.

> 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}}
