Code works for multiple views but my output only works for 1 view.
After hours of trying i ask for help again.
I don´t know how to deal with the sublists:
Working for only one view:
startpointList = []
endpointList = []
rotationAngleList = []
for newGLine in newGLineList:
startpointXYZ = newGLine.GetEndPoint(0)
endpointXYZ = newGLine.GetEndPoint(1)
startpoint = startpointXYZ.ToPoint()
endpoint = endpointXYZ.ToPoint()
startpointList.append(startpoint)
endpointList.append(endpoint)
vector = newGLine.Direction
rotationAngle = abs(math.degrees(vector.AngleOnPlaneTo(activView.RightDirection, XYZ.BasisZ)))
rotationAngleList.append(rotationAngle)
OUT = lstInputViews, rotationAngleList
One of my failed attempts:
startpointList = []
endpointList = []
rotationAngleList = []
for newGLines in newGLineList:
for newGLine in newGLines:
I got many differenht lists, for example sublists with too many items…but i can´t get the result i want 
Maybe i have to use this mysteriouse [x for x in y] thing i don´t understand.
I don´t think i have to zip lists together in this case?
Happy about any help 
thanks!
edit:
The problem has to be something even before, because newGLineList ist also only a list for 1 view.

How can i do that?
