Using webcam to capture video with OpenCv in Python

I'm learning OpenCV, and need to access the input from the webcam using VideoCapture(0). Unfortunately, I'm not getting anything from the webcam.

I'm unsure if this is a bug with Spyder, or an issue with my code.

My code reads -

cap = cv2.VideoCapture(0)
while (1):
    _, frame = cap.read()
    display(frame)

Display is a tried-and-true function that displays a picture.

Does anyone know what my issue might be?

EDIT - This is an issue with Spyder's implementation, so although it wasn't displaying, I was in fact getting input from the webcam.

I dont thing it is spyder, you must wait for the camera to generate the next picture, like in here: https://stackoverflow.com/questions/2601194/displaying-a-webcam-feed-using-opencv-and-python – Victor Jul 23 '17 at 23:11

Personally I am using Spyder too (with the ipython console) and I have no problem to grab a camera frame. However, I cannot display frames / images / plot from any Python debugger, and this is known issue. – Vincent Vidal Jul 24 '17 at 09:54
