Why isn't Opencv-python showing my camera feed?

Question

Ok so I wanted to open my webcam feed in opencv python. When I run the code, it opens up a blank window and later says "Python has stopped working."I want to know why is it happening and how do I solve it !!!! Here is the code:

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

while(True):
    ret, frame = cap.read()
    gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)

    cv2.imshow('frame',gray)
    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

I am using Spyder which I installed from Anaconda. I also tried the same code on jupyter notebook and also on the original python 3.8 software. The results were same.Here is an image of what I am facing:Problem image. For any clarification...please comment!!!

Answer 1

No problem with the code . Make sure you have a webcam in which you are running the program.

cv2.VideoCapture(index)

The index in videoCapture indicates video capturing device to open. To open default camera 0 is used.
