WebThis operator will group the values coming from the source observable based on the key_mapper function given. Syntax group_by (key_mapper) Parameters key_mapper: This function will take care of extracting keys from the source observable. Return value It returns an observable with values grouped based on the key_mapper function.

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 ...
