Define A Decorator Function Log

And the result should be something like.

Define a decorator function log. When a class is instantiated. My current implementation is this. Where every argument passed as a parameter to the function is showed with its value.

A function that takes another function as an argument generates a new function augmenting the work of the original function and returning the generated function so we can use it anywhere. The decorator acts as a wrapper. We can see that the decorator function added some new functionality to the original function.

But now it looks pretty since it got decorated. In this example we re going to implement a decorator that. I want to make a function that being a decorator to another function will print that function call details parameters names and effective values.

Stdout accessed the function with arguments format func name args kwdargs return stdout return inner def greet msg. This sounds confusing but it s really not especially after you ve seen a few examples of how decorators work. This is similar to packing a gift.

Decorator to print function call details. Def inner args kwdargs. To have get text itself be decorated by p decorate we just have to assign get text to the result of p decorate.

The nature of the object that got decorated actual gift inside does not alter. Decorators are a sort of syntactic sugar for something very simple. Log def f a b 2 c d.
