Hello,
I'm working on an application in which I need the main loop to call the
same method on a number of objects. I came up with this solution that
seem to work, but I was wondering if there is a better / more pythonic
solution to the problem.
<code>
def invokeAll(method, data):
"""This function is a dispatcher: it invokes all the content types
of the application calling 'contenttype.method(data)'"""
return [getattr(content, method)(data) for content in contents]
</code>
I am also unsatisfied by how I generate the content list I use in the
above function. In fact, as I have the need to access the object both
individually and with the dispatcher, I am doing something like this
every time I instantiate a new object:
<code>
mycontent = ContentA()
contents.append(mycontent)
</code>
...but although I "feel" this is silly, I can't imagine how to get it
better (i.e. a single call that will make available the object with his
unique name and append it to the list of contents.
Thank you in advance for your input,
Mac.
