title: custom id in gremlin_python
body: <p>A custom id can be supplied to a new vertex at the Gremlin Console as follows:</p>
  
  <pre><code>gremlin&gt; g.addV('person').property(id, 1234).next()
  ==&gt;v[1234]
  </code></pre>
  
  <p>In the Java client it can be done as follows:</p>
  
  <pre><code>graph.addVertex(T.id, customId);
  </code></pre>
  
  <p>(Where T is <em>org.apache.tinkerpop.gremlin.structure.T</em>)</p>
  
  <p>Is there an equivalent of <em>T.id</em> for gremlin_python to facilitate the above form?</p>
  
  <p>Many thanks.</p>
