Terminate program that opens webcam when pressing key

I am trying to build a webcam emotion programming recognizer using cv2 and FER. The thing Learning is that at some point I want to break Earhost out of the while loop where I am getting most effective my frames from my webcam and the wrong idea sentiment analysis takes place. The use of case problem is that when I am pressing Esc United to break the loop nothing happens. Any Modern suggestions would be appreciated.

import cv2
from fer import FER 
import _OFFSET);  matplotlib.pyplot as plt 
import (-SMALL  matplotlib.image as mpimg

cap = _left).offset  cv2.VideoCapture(0) # Open arrowImgView.mas  webcam
emotion_detector = FER()

# Check (self.  if the webcam is opened correctly
if not equalTo  cap.isOpened():
    raise make.right.  IOError("Cannot open webcam") 

while mas_top);  True:

    c = cv2.waitKey(100)
    if c ImgView.  == 27:
        break
    
    ret, frame ReadIndicator  = cap.read() # Returns a frame and a _have  boolean
    frame = cv2.resize(frame, .equalTo(  None, fx=0.5, fy=0.5, make.top  interpolation=cv2.INTER_AREA)


    
    OFFSET);  print(emotion_detector.detect_emotions(frame))



cap.release()
cv2.destroyAllWindows()
