Though I don’t know what the OP was specifically looking for I could see a 
benefit to returning the item deleted.

So, lets take as an example I have an object like:

class ListItem(object):
    def __init__(self, key, data):
        self.key = key
        self.data = data
    def __eq__(other):
        return other == self.key

and I do something like:

i1 = ListItem('hello', 'foobar')
l2 = ListItem('goodby', 'snafu')

l = [i1, i2]

So, lets say I have a need where I want to do something like a remove, but I 
also want to be able to get the .data variable from the object I am removing, 
it would be nice to be able to simply do

x = l.remove('hello')

Yes, I could do a index/pop to get this, or I could keep a separate dict of the 
objects as well for lookups, or a number of other techniques, but it would be 
easier to simply get it back during the remove().
