Here, predicate is a function being called each time an item is emitted from the source observable. When the predicate function returns True, then the skip_while operator starts emitting items of the source observable.

Here is an example of the skip_while operator:

numbers = Observable.from_([1, 2, 3, 4])numbers.skip_while(lambda i: i < 2).subscribe( ...
