qgis 3 - Selecting only visible features from different layers using PyQGIS

I want to control whether features from different layers are visible. These features are in a list.

I found a script in qgis api but I can not use it:

if not renderer.capabilities().testFlag(QgsFeatureRenderer.Filter) or renderer.willRenderFeature(feature, context):

    deal_with_my_feature()
else:
    skip_the_curren_feature()
