Lets say my class has many methods, and I want to apply my decorator on each one of them, later when I add new methods, I want the same decorator to be applied, but I dont want to write @mydecorator above the method declaration all the time? If I look into __call__ is that the … Read more
Let’s say I have the following:
I don’t really need to do this, but was just wondering, is there a way to bind a decorator to all functions within a class generically, rather than explicitly stating it for every function.
I have a function with a decorator that I’m trying test with the help of the Python Mock library. I’d like to use mock.patch to replace the real decorator with a mock ‘bypass’ decorator which just calls the function.
So, I’m playing with decorators in Python 2.6, and I’m having some trouble getting them to work. Here is my class file:
def make_bold(fn): return lambda : "<b>" + fn() + "</b>" def make_italic(fn): return lambda : "<i>" + fn() + "</i>" @make_bold @make_italic def hello(): return "hello world" helloHTML = hello() Output: “<b><i>hello world</i></b>” I roughly understand about decorators and how it works with one of it in most examples. In this example, there are 2 … Read more
I’d like to create a Python decorator that can be used either with parameters:
I have something roughly like the following. Basically I need to access the class of an instance method from a decorator used upon the instance method in its definition.
I have a problem using docstrings with decorators. Given the following example:
I’m trying to find a way to make a decorator that does something like injecting a name into the scope of another function (such that the name does not leak outside the decorator’s scope). For example, if I have a function that says to print a variable named var that has not been defined, I would like to define it within a decorator where it is called. Here is an example that breaks:
