    • Helper tools to add annotations to existing code

      • pytype annotate-ast - A work-in-progress tool to annotate the nodes of an AST with their Python types.
      • jsonschema-gentypes - Generate Python types based on TypedDict from a JSON Schema.
      • pytype annotate-ast - A work-in-progress tool to annotate the nodes of an AST with their Python types.

      • PyTypes - Infer Types by Python Tracing.
      • pyre infer - Pyre has a powerful feature for migrating codebases to a typed format. The [infer](https://pyre-check.org/docs/pysa-coverage/) command-line option ingests a file or directory, makes educated guesses about the types used, and applies the annotations to the files.
