Hands-On Reactive Programming with Python

Filtering observables

The operators listed here emit only some of the items emitted on the source observables, based on their criteria. Some of them have already been covered in the previous chapters. They are the following:

Operator	Description	Chapter
debounce	Maps each item to another value	8
distinct_until_changed	Emits an item only when it is different from the previously emitted item	8
filter	Emits only items that meet a certain criterion	6
skip	Skips items some amount of items	6
take	Emits only some amount of items	8
