python-introspect 0.1.2

Pure Python introspection toolkit for function signatures, dataclasses, and type hints

python-introspect

Pure Python introspection toolkit for function signatures, dataclasses, and type hints

Features

• 🔍 Function/Method Signature Analysis - Extract parameter info from any callable
• 📦 Dataclass Field Extraction - Analyze dataclass fields and types
• 📝 Docstring Parsing - Extract and parse docstrings (Google, NumPy, Sphinx styles)
• 🏷️ Type Hint Resolution - Resolve complex type hints and annotations
• 🎯 Unified API - Single interface for all parameter sources
• 🚀 Pure Python - No external dependencies, pure stdlib

Installation

pip install python-introspect

Quick Start

from python_introspect import SignatureAnalyzer

def example_function(name: str, age: int = 25, *, active: bool = True):
    """
    Example function with parameters.
    
    Args:
        name: The person's name
        age: The person's age
        active: Whether the person is active
    """
    pass

# Analyze the function
analyzer = SignatureAnalyzer()
params = analyzer.analyze_function(example_function)

for param in params:
    print(f"{param.name}: {param.annotation} = {param.default}")

Use Cases

• Form Generation - Generate UI forms from function signatures
• API Documentation - Auto-generate API docs from code
• Configuration Validation - Validate config against function parameters
• Dynamic UI - Build dynamic UIs based on function signatures
• Parameter Analysis - Analyze and validate function parameters
