public class PythonTranslateVisitor
extends AbstractTranslateVisitor

Converts a Gremlin traversal string into a Python source code representation of that traversal with an aim at sacrificing some formatting for the ability to compile correctly.

• Range syntax has no direct support
• Normalizes whitespace
• If floats are not suffixed they will translate as BigDecimal
• Makes anonymous traversals explicit with double underscore
• Makes enums explicit with their proper name
