The issue with Pylance expecting an expression or "." or "(" not being closed is likely due to syntax errors in my code, but where?

Question

Someone suggested this but it DOESN'T work either.

In the line AVCaptureDevice.requestAccess (for: .video), the parenthesis around for: .video should be removed as it is not a valid syntax in Python. Instead, you should separate the keyword argument for and its value .video with a comma.

In the line AVCaptureDevice.authorizationStatus, the dot notation is not correct. You should use the square brackets notation to access the authorizationStatus attribute of the AVCaptureDevice class.

Here is my code:

import cv2
import numpy as np
from AVFoundation import AVCaptureDevice

class Camera(object):
    def __init__(self, camera=0):
        AVCaptureDevice.requestAccess(for: .video) { granted in
            if granted:
                self.cam = cv2.VideoCapture(camera)
                self.valid = False
                try:
                    resp = self.cam.read()
                    self.shape = resp[1].shape
                    self.valid = True
                except:
                    self.shape = None
            else:
                print("Permission to access camera was denied.")
                self.valid = False
        }

    def get_frame(self):
        if self.valid:
            _, frame = self.cam.read()
        else:
            frame = np.ones((480, 640, 3), dtype=np.uint8)
            col = (0, 256, 256)
            cv2.putText(frame, "(Error: Camera not accessible)",
                        (65, 220), cv2.FONT_HERSHEY_PLAIN, 2, col)
        return frame

    def release(self):
        self.cam.release()

Help me to resolve this "syntax error" so I can compile the code to execute a functional py2app.
