decorator-once-per-minute

Goal: Run the provided function once per minute, using a decorator.

Problem: How can you preserve state across multiple function runs -> nonlocal

def once_per_minute(func):
    last_invoked = 0 # <-- Keep the state in the parent function

    def wrapper(*args, **kargs):
        nonlocal last_invoked  # <----
        elapsesd_time = time.time() - last_invoked
        if elapsed_time < 60:
            raise CalledToOftenError(f"Only {elapsed_time} passed
        last_invoked = time.time()
        return func(*args, **kargs)

    return wrapper
