collections' `popitem(~)` method removes a key-value pair from an ordered dictionary and returns it.

# Parameters

1. `last` | `boolean` | `optional`

If `True` pairs are returned in LIFO order, if `False` pairs are returned in FIFO order. Defaults to `True`.

# Return value

The removed key-value pair.

# Examples

To remove and return the last inserted key-value pair (LIFO):

``` from collections import OrderedDictod = OrderedDict([('key1', 1), ('key2', 2), ('key3', 3)])od.popitem(last=True) ('key3', 3) ```

To remove and return the first inserted key-value pair (FIFO):

``` from collections import OrderedDictod = OrderedDict([('key1', 1), ('key2', 2), ('key3', 3)])od.popitem(last=False) ('key1', 1) ```
