Restricting the layout elements returned by ListLayoutElements()

Layouts can contain a large number of elements, many of which you won't need for a particular geoprocessing script. The ListLayoutElements() function can restrict the layout elements returned, by passing a parameter that defines the type of element that should be returned along with an optional wildcard, which finds elements using a portion of the name.

Getting ready

There are many different types of layout elements, including graphics, legends, pictures, text, and data frames. When you return a list of layout elements, you can restrict (filter) the types of elements that are returned. In this recipe, you will write a script that filters the layout elements returned by element type and wildcard.

How to do it…

Follow these steps to learn how to restrict the list of layers returned by the ListLayoutElements() function through the use of optional parameters, which define the type of element that should be returned along...
