Using the [Element.Name](http://www.revitapidocs.com/2018.1/e372092e-ff47-71c2-1272-50ab08e5a41d.htm) property you can do this quite easily. The following expects `IN[0]` to be a list of elements. You can also greatly reduce the redundancy in your script by defining a custom function:

```
import clr
clr.AddReference('RevitAPI')
from Autodesk.Revit.DB import *

def filter_list(elements, search_str):
	"""Given a list of Views, returns only those which
	contain a given string in their name"""
	passed = []
	for element in elements:
		name = element.Name
		if search_str in name:
			passed.append(element)
	return passed

views = [UnwrapElement(view) for view in IN[0] if view is not None]
nwc = filter_list(views, 'NWC')
elec = filter_list(views, 'ELEC')

OUT = nwc, elec

```

[views.dyn](https://forum.dynamobim.com/uploads/short-url/3riACz4vwJGGpgltK9ezI03zTn3.dyn) (5.1 KB)

This could also be easily modified to accept a list of strings to test (e.g. `["NWC", "ARCH", "STRC"...]`) since you’re combining all of the lists anyway.
