Instead, Python allows you to use decorators in a simpler way with the@symbol, sometimes called the“pie” syntax. The following example does the exact same thing as the first decorator example: defmy_decorator(func):defwrapper():print("Something is happening before the function is called.")...
Simple exampleIn the next example, we create a simple decorator example. main.py #!/usr/bin/python def enclose(fun): def wrapper(): print("***") fun() print("***") return wrapper def myfun(): print("myfun") enc = enclose(myfun) enc() The enclose function is a decorator...
In the above example, thereturn hellostatement returns the innerhello()function. This function is now assigned to thegreetvariable. That's why, when we callgreet()as a function, we get the output. Python Decorators As mentioned earlier, A Python decorator is a function that takes in a func...
Decorators are a powerful feature in Python that allows you to modify or extend the behavior of functions or classes without changing their actual code. Decorators are widely used for logging, access control, instrumentation, and more. This tutorial will focus on understanding function decorators and...
In Python, we can also return a function as a return value. For example, defgreeting(name):defhello():return"Hello, "+ name +"!"returnhello greet = greeting("Atlantis")print(greet())# prints "Hello, Atlantis!"# Output: Hello, Atlantis!
In the following example, you rewrite parent() to return one of the inner functions:Python inner_functions.py def parent(num): def first_child(): return "Hi, I'm Elias" def second_child(): return "Call me Ester" if num == 1: return first_child else: return second_child ...
Instead, Python allows you to use decorators in a simpler way with the@symbol, sometimes called the“pie” syntax. The following example does the exact same thing as the first decorator example: defmy_decorator(func):defwrapper():print("Something is happening before the function is called.")...
Explore decorators in Python to extend and modify the behavior of functions or methods. Learn how to apply, chain, and create decorators for cleaner, reusable code.

After all, what I just mentioned sounded quite abstract, and it might be difficult to see how decorators can benefit you in your day-to-day work as a Python developer. Let me try to bring some clarity to this question by giving you a somewhat real-world example: ...
