Python decorator gives us the ability to add new behavior to the given objects dynamically. In the example below, we’ve written a simple example to display a message pre and post the execution of a function.
def decorator_sample(func):
def decorator_hook(*args, **kwargs):
print("Before the function call")
result = func(*args, **kwargs)
print("After the function call")
return result
return decorator_hook
@decorator_sample
def product(x, y):
"Function to multiply two numbers."
return x * y
print(product(3, 3))
The output is:
Before the function call
After the function call
