Python CV2 "AttributeError: module 'cv2.aruco' has no attribute 'Dictionary_get'. Did you mean: 'Dictionary'?"

Question

I tried to run this code but it gives error.

import cv2

arucoDict = cv2.aruco.Dictionary_get(cv2.aruco.DICT_6X6_50)
arucoParams = cv2.aruco.DetectorParameters_create()
(corners, ids, rejected) = cv2.aruco.detectMarkers("arucoimg.png", arucoDict, parameters=arucoParams)

print(corners, ids, rejected)

I can't finish rest of the code due to this problem. However I copied that code on the Internet.
