How do I get the list of Levels using Python?

I am trying to get the list of Levels using Python in order to create a plan per level & phase.
I get the Phases using doc.Phases. ( doc = revit.ActiveUIDocument.Document)
I could not find the way to access the Levels in a similar way.
Thanks , Jonathan.

Thanks @fathygad .
I can undestand from the naming convention the FilteredElementCollector.ofCategory.
What is the purpose of the WhereElementIsNotElementType().ToElements() part ?

@jonathan.talisman IF U don’t use u will get the element (Level) and the Element type , so if u have 10 level u will get 20 item output 10 for levels them selves and other 10 for their types.
