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')
print(x.data)
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().
