title: TypeError : 'list' object is not callable
body: <p>i was working with face mesh module of opencv to detect my face<br />
  when i try to run it on my code editor it show
  &quot;landmarks = landmark_points(1).landmark&quot; this list as not callable</p>
  <pre><code>import cv2
  import mediapipe as mp
  
  from cv2 import _registerMatType
  
  
  cam = cv2.VideoCapture(0)
  
  face_mesh = mp.solutions.face_mesh.FaceMesh()
  
  while True: 
  
      _, frame = cam.read()
  
      rgb_frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)
      
      #to get face detected
      output = face_mesh.process(rgb_frame)
      landmark_points = output.multi_face_landmarks
      
      #to get coordinates of face 
      if landmark_points:
          landmarks = landmark_points(1).landmark
          for landmark in landmarks:
              x = landmark.x
              y = landmark.y
              print(x, y)
  
      #frame display
      cv2.imshow('face detection', frame)
  
      if cv2.waitKey(1) &amp; 0xFF == ord('q'):
  
          break
  
  cam.release
  
  cv2.destroyAllWindows()
  </code></pre>
  <p>the code work properly if we replace the coordinate section with &quot;print(landmark_points)&quot;
  but i can not use the then result for my purpose, as i want it in (x,y) format</p>
  <p>tried some sources but could not understand problem.
  can some one provide solution with expanation?</p>
