Is the error message not clear enough? You have a 'break' command outside of a loop. If the error message is not clear enough, please suggest something that would be more clear. Also, you should read the entire traceback, which will show you not just the error, but the exact line causing the problem. For example, these two are legal: # Legal while x > 100: if y == 0: break ... # Also legal for i in range(1000): if x > 20: break ... But not this: # Not legal if x > 20: break You can't break out of a loop, if you aren't inside a loop to begin with. > while (1): > _, frame = cap.read() You have a while loop with only one line. It loops forever, and never exits. Are you sure that's what you want? By the way, it is much, much, much easier to see indentation when you make it four spaces or eight. Good programmer's editors let you set indentation to four or eight spaces. Even Notepad, which is *not* a programmer's editor, lets you hit the Tab key and indent. > hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV) Because this line is not indented, it is not inside the loop. > if k == 27: > > break Again, because the "if" line is not indented, it is outside the loop, and so the break is illegal. -- Steven ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

[Tutor] Error :SyntaxError: 'break' outside loop
Hi everyone I write this code for color segmentation ,but after Run I recived this error: SyntaxError: 'break' outside loop I could not resolve that ,could you please help me? python.2.7.5 import cv2 import numpy as np cap = cv2.VideoCapture("C:\Users\Zohreh\Desktop\Abdomen.MST") while (1): _, frame = cap.read() hsv = cv2.cvtColor(frame, cv2.COLOR_BGR2HSV) lower_blue = np.array([110,50,50]) upper_blue = np.array([130,255,255]) mask = cv2.inRange(hsv, lower_blue, upper_blue) res = cv2.bitwise_and(frame,frame, mask= mask) cv2.imshow("frame",frame) cv2.imshow("mask",mask) cv2.imshow("res",res) k = cv2.waitkey(5) & 0xFF if k == 27: break cv2.destroyWindow() ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
