NameError: name 'ClasscadeClassifier' is not defined

edit

can you please fix the following error faceDetect=ClasscadeClassifier('haarcascade_frontalface_default.xml'); NameError: name 'ClasscadeClassifier' is not defined ( I have saved the casscade file to where I am working)

my code

import cv2
import numpy as np




faceDetect=ClasscadeClassifier('haarcascade_frontalface_default.xml');
cam=cv2.VideoCapture(1);

while(True):
    ret,img=cam.read();
    gray=cv2.cvtColor(img,cv2.COLOR_BGR2GRAY)
    faces=faceDetect.detectMultiScale(gray,1.3,5);
    for(x,y,w,h) in faces:
        cv2.rectangle(img,(x,y),(x+w,y+h),(0,0,255),2)
        cv2.imshow("Face",img);
        if(cv2.waitKey(1)==ord('q')):
            break;
        cam.release()
        cv2.destroyAllWindows()
