Pretty sure you're looking for:yourCamVar.isOpened(). This checks if it's capturing video.

Lots of information on that here.

import numpy as np
import cv2

cap = cv2.VideoCapture(0)

while(True):
    # Capture frame-by-frame
    ret, frame = cap.read()

    if cap.isOpened():
        print("Webcam online.")

# When everything done, release the capture
cap.release()
cv2.destroyAllWindows()
