A decorator that keep track of a function when it has been called. This is good for viewing recursion

log_function_call.py

import functools

def log_function_call(func):
    @functools.wraps(func)
    def wrapper(*args, **kwargs):
        print(f"Calling {func.__name__} with args: {args}, kwargs: {kwargs}")
        result = func(*args, **kwargs)
        print(f"{func.__name__} returned: {result}")
        return result
    return wrapper

def recursive_factorial(n):
    if n == 0 or n == 1:
      return 1
    else:
        return n * recursive_factorial(n - 1)

# Test the recursive function
result = recursive_factorial(4)
