The :mod:`queue` module implements multi-producer, multi-consumer queues.
It is especially useful in threaded programming when information must be
exchanged safely between multiple threads. The :class:`Queue` class in this
-module implements all the required locking semantics. It depends on the
-availability of thread support in Python; see the :mod:`threading`

The module implements three types of queue, which differ only in the order in
which the entries are retrieved. In a :abbr:`FIFO (first-in, first-out)`
