run_n_times()

Here's an example of a run_n_times decorator that can be used to execute a function a specified number of times:

def run_n_times(n):

def decorator(func):

def wrapper(*args, **kwargs):

for i in range(n):

func(*args, **kwargs)

return wrapper

return decorator

This decorator takes an integer n as an argument and returns a decorator that takes a function as its argument. The returned decorator wraps the original function with a loop that executes it n times. The wrapper function returns None because it doesn't need to return a value.

Here's an example of how to use this decorator to execute a function three times:

@run_n_times(3)

def say_hello(name):

print(f"Hello, {name}!")

say_hello("Alice")

Output:

Hello, Alice!

In this example, the say_hello function is decorated with the run_n_times decorator with n=3. When the function is called with the argument "Alice", the decorator executes it three times, printing "Hello, Alice!" each time.

Note that the run_n_times decorator can be used with any function that takes any number of arguments. It's a simple example of how decorators can be used to add functionality to existing functions without modifying their code.
