Trying to find examples of when decorators might be really beneficial, and when not so much. Sample code is appreciated.

I added the location of PIL and psycopg2 to PATH.
I know that Terminal is…

I want to pass a chunk of Python code to Python in R with something like system('python ...'), and I'm wondering if there is an easy way to emulate the python console in this case. For example, suppose the code is "print 'hello world'", how can I get the output like this in R?

Hi,
I am currently struggling to call a non python program from a python script.
I have a ~1000 files that when passed through this C++ program will generate ~1000 outputs. Each output file must have a distinct name.
The command I wish to run is of the form:
program_name -input -output -o1 -o2…

Goal: Make it possible to decorate class methods. When a class method gets decorated, it gets stored in a dictionary so that other class methods can reference it by a string name.
Motivation: I want to implement the equivalent of ASP.Net's WebMethods. I am building this on top of google app engine…

My decorator looks like this:
class plot_svg(object):
def __init__(self, view):
self.view = view

I'm writing some unit tests for a Django project, and I was wondering if its possible (or necessary?) to test some of the decorators that I wrote for it.
Here is an example of a decorator that I wrote:
class login_required(object):
def __init__(self, f):
self.f = f
def __call__(self,…

Help a guy out. Can't seem to get a decorator to work with inheritance. Broke it down to the simplest little example in my scratch workspace. Still can't seem to get it working.
class bar(object):
def __init__(self):
self.val = 4
def setVal(self,x):
self.val = x

I'm trying to figure out how to use decorators on subclasses that use super(). Since my class decorator creates another subclass a decorated class seems to prevent the use of super() when it changes the className passed to super(className, self). Below is an example:
def class_decorator(cls):
