How can I use decorators to improve performance in my code?

You can use decorators to cache results, log execution time, or even manage resource usage, which can enhance performance.

Can you give me an example of a caching decorator?

Sure! Here's a simple caching decorator that stores results in a dictionary:

def cache(func):
    results = {}
    def wrapper(*args):
        if args not in results:
            results[args] = func(*args)
        return results[args]
    return wrapper

How does this caching decorator work?

It checks if the result for the given arguments is already cached. If not, it calls the function and stores the result.

Are there any performance drawbacks to using decorators?

Yes, if not implemented carefully, decorators can add overhead, especially if they perform complex operations or if they are used excessively.
