Python Isn't Java

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

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.
• Semaphore.acquire() cannot be interrupted. There is no tryAcquire() method either.
• Conditions can only be interrupted by the notifier.
