What are some examples of performance decorators in Python?

Performance decorators in Python are functions that modify the behavior of other functions to enhance their performance. For example, you can use a decorator to measure the execution time of a function.

Can you show me a code example of a performance decorator?

Sure! Here's a simple example:

import time

def time_decorator(func):
    def wrapper(*args, **kwargs):
        start_time = time.time()
        result = func(*args, **kwargs)
        end_time = time.time()
        print(f"Execution time: {end_time - start_time} seconds")
        return result
    return wrapper

@time_decorator
def my_function():
    time.sleep(2)
    print("Function executed!")

my_function()

What other use cases do performance decorators have?

Performance decorators can be used for caching results, logging function calls, and even retrying failed operations, among other things.
