Iterate over (item, others) in a list

Question

Suppose I have a list:

l = [0, 1, 2, 3]

How can I iterate over the list, taking each item along with its complement from the list? That is,

for item, others in ...
    print(item, others)

would print

0 [1, 2, 3]
1 [0, 2, 3]
2 [0, 1, 3]
3 [0, 1, 2]

Ideally I'm looking for a concise expression that I can use in a comprehension.

Answer 1

This is quite easy and understandable:

for index, item in enumerate(l):
    others = l[:index] + l[index+1:]

You could make an iterator out of this if you insist:

def iter_with_others(l):
    for index, item in enumerate(l):
        yield item, l[:index] + l[index+1:]

Giving it's usage:

for item, others in iter_with_others(l):
    print(item, others)
