====== Python Isn't Java ======

Some things in Python are infeasible to implement as they existed in Java.  This page lists some things.


==== Threading ====
Python has threads, but there are several limitations.

  * When a Future is cancelled, the task is not aware of the cancellation.  This is because there is no `mayInterruptIfRunning`.  This means cancelling a future just marks the future as cancelled, but doesn't actually notify they threads they should stop.
  * There is no thread interruption.   It's not possible to stop waiting on several core types.
  * [[https://docs.python.org/3.13/library/threading.html#threading.Semaphore.acquire|Semaphore.acquire()]] cannot be interrupted.  There is no ''tryAcquire()'' method either.
  * Conditions can only be interrupted by the notifier.
