Break should be inside the while loop. to be inside, you need to add indentation, like this:
import cv2
import sys
cpt=0
vidStream=cv2.VideoCapture(0)
while True:
ret,frame=vidStream.read()
cv2.imshow("Test Frame", frame)
cv2.imwrite(r"E:\Face_Detection_Project\Test_images\0\image%04i.jpg" %cpt,frame)
cpt +=1
if cv2.waitKey(10)==ord('q'):
break

break is used to break off from a loop. Outside a loop, break statement has no scope. You should put it inside the while loop. Read the break documentation for more information.

I am trying to run this code but on localhost it just comes back as the lines of code. What might be the issue?
