Hello,

    else: return [x]

#collector
collector = FilteredElementCollector(doc).OfCategory(BuiltInCategory.OST_Doors)
all_elements = collector.WhereElementIsNotElementType().ToElements()

onHand = [ i.HandFlipped for i in all_elements] # is LE
onFace = [ i.FacingFlipped for i in all_elements] # is LE
bothFaceHand = [ i.FacingFlipped and i.HandFlipped for i in all_elements] # is RE
bothHandFace = [ i.HandFlipped and i.FacingFlipped for i in all_elements] #  is RE
#rest is RE

_onHand = [p for p in onHand if i.Replace(True,"LE")]

OUT = _onHand

Replace does not work

Is this what you are trying to do?
[True for p in onHand if p == "LE" else p]
or
["LE" for p in onHand if p == True else p]

idea is to create a “flipmatrix” so you can see if door is correct string value vs visual representation!

So my understanding is that if facing and handing are different (True / False | False / True) = RE
This is an XOR logic which would imply a comprehension like this
["LE" for i in all_elements if i.FacingFlipped == i.HandFlipped else "RE"]
True/True and False/False evaluate as True whereas True/False and False/True evaluate as False
