2. Debugging Tools

python

# debug_tools.py
import pdb
import logging
import inspect
import traceback
from functools import wraps
def debug_on_error(func):
    """Decorator to drop into debugger on exception"""
    @wraps(func)
    def wrapper(*args, **kwargs):
        try:
            return func(*args, **kwargs)
        except Exception:
            traceback.print_exc()
            pdb.post_mortem()
            raise
    return wrapper
def log_function_calls(func):
    """Decorator to log function calls"""
    @wraps(func)
    def wrapper(*args, **kwargs):
        logger = logging.getLogger(func.__module__)
        logger.debug(f"Calling {func.__name__} with args={args}, kwargs={kwargs}")
        result = func(*args, **kwargs)
        logger.debug(f"{func.__name__} returned {result}")
        return result
    return wrapper
