2-Minute Guide: Decorators in Python
Hey there, Python enthusiasts! Today, we're going to explore one of the coolest features in Python: decorators. So, what's a decorator? In simple terms, a decorator is a small function that can modify or extend the behavior of another function without permanently changing it.
Think of a decorator as a wrapper that adds some extra functionality to an existing function. It's like adding a new feature to a car without altering its original design. You can use decorators to log function calls, measure execution time, or even implement authentication checks.
Let's see a minimal example of a timer decorator:
python
import time
from functools import wraps
def timer_decorator(func):
@wraps
