Introduction
Do you want to take your Python skills to the next level? By learning how to use decorators and abstraction effectively, you can greatly improve the readability, maintainability, and efficiency of your code.
This article will explain what these concepts are and provide clear, concise examples so that you can start using them right away.
What are Decorators?
A decorator is a special type of function that allows you to add extra functionality to an existing function or method without having to modify its source code directly. It’s like giving a superpower to your function! You simply wrap it with a decorator and voila, it now has new abilities.
Here’s an example of a simple decorator that logs the execution time of a function:
import time
def log_execution_time(func):
def wrapper(*args, **kwargs):
start = time.time()
result = func(*args, **kwargs)
end = time.time()
print(f"{func.__name__} took {end - start} seconds")
return result
return…
