make function decorator python code example

Example: python decorator

# Decorator with arguments
import functools

# First function takes the wanted number of repetition
def repeat(num_times):
    # Second function takes the function
    def decorator_repeat(func):
        # Third function, the wrapper executes the function the number of times wanted        
        # functools decorator to print the true name of the function passed instead of "wrapper"
        @functools.wraps(func)
        def wrapper(*args, **kwargs):
            for _ in range(num_times):
                result= func(*args, **kwargs)
            return result
        return wrapper
    return decorator_repeat

# Our function using the decorator
@repeat(num_times= 3)
def greet(name):
    print(f"Hello {name}")

greet("thomas")
