fortplot_python_interface

Python interface module for F2PY binding generation

This module provides a clean interface for Python bindings using F2PY. It exposes the essential functions needed for simplified Python show() API.

Key functions: - show_figure(blocking): Direct call to Fortran show with blocking parameter - show_viewer(blocking): Direct call to Fortran show_viewer with blocking parameter - All other plotting functions for complete API coverage

Uses

- fortplot_matplotlib
- iso_fortran_env
