The "float" property aliases the "float" type and completely breaks the

"float" property instead.

* python: several typing and style improvements
The generated (python) code fails with several standard validation tools,
including `flake8`, `mypy`, and `autoflake`. While fixing every possible
violation -- especially wrto typing -- woudl be a project, some of the
changes are fairly easy.
- The `autoflake` tool picks up on unused imports. These can just be removed.
- The `mypy` tool picks up on numerious typing violations, especially if set
to its strictest mode. As a starting point, all functions ought to annotate
a return type, including constructors, even if the return type is `None`
because otherwise the functions are omitted from type checking and it's
impossible to make incremental progress towards adding types.
- The `flake8` tool mostly finds whitespace and line-length issues; while
line-length standards very, the source already includes several flake8
ignores, so it seems safe to add a few more.
* Add generated files
* Restore imports used by `AbstractPythonCodegen.java`
* Update generated files
