### class Empty
     |  Exception raised by Queue.get(block=0)/get_nowait().

### class SimpleQueue
     |  Simple, unbounded, reentrant FIFO queue.
     |
     |  Methods defined here:
     |
     |  empty(self, /)
     |      Return True if the queue is empty, False otherwise (not reliable!).
     |
     |  get(self, /, block=True, timeout=None)
     |      Remove and return an item from the queue.
     |
     |      If optional args 'block' is true and 'timeout' is None (the default),
     |      block if necessary until an item is available. If 'timeout' is
     |      a non-negative number, it blocks at most 'timeout' seconds and raises
     |      the Empty exception if no item was available within that time.
     |      Otherwise ('block' is false), return an item if one is immediately
     |      available, else raise the Empty exception ('timeout' is ignored
     |      in that case).
     |
     |  get_nowait(self, /)
     |      Remove and return an item from the queue without blocking.
     |
     |      Only get an item if one is immediately available. Otherwise
     |      raise the Empty exception.
     |
     |  put(self, /, item, block=True, timeout=None)
     |      Put the item on the queue.
     |
     |      The optional 'block' and 'timeout' arguments are ignored, as this method
     |      never blocks.  They are provided for compatibility with the Queue class.
     |
     |  put_nowait(self, /, item)
     |      Put an item into the queue without blocking.
     |
     |      This is exactly equivalent to `put(item)` and is only provided
     |      for compatibility with the Queue class.
     |
     |  qsize(self, /)
     |      Return the approximate size of the queue (not reliable!).
     |

     |  Class methods defined here:
     |

     |
     |  ----------------------------------------------------------------------
     |  Static methods defined here:
     |

     |      Create and return a new object.  See help(type) for accurate signature.
