WebRxPY - Concurrency using Scheduler. One important feature of RxPy is concurrency, i.e. to allow the task to execute in parallel. To make that happen, we have two operators subscribe_on () and observe_on () that will work with a scheduler, that will decide the execution of the subscribed task. Here, is a working example, that shows the need for ...
