Using 'in' to match an attribute of Python objects in an array

Question

I don\'t remember whether I was dreaming or not but I seem to recall there being a function which allowed something like,

foo in iter_attr(array of python ob         


        

Answer 1

you could always write one yourself:

def iterattr(iterator, attributename):
    for obj in iterator:
        yield getattr(obj, attributename)

will work with anything that iterates, be it a tuple, list, or whatever.

I love python, it makes stuff like this very simple and no more of a hassle than neccessary, and in use stuff like this is hugely elegant.
