[BangPypers] how to see each line result in python

[narayan naik]

hi,
i have face detection code as

import cv2
import sys


def detect(path):
    img = cv2.imread(path)
    cascade =
cv2.CascadeClassifier("/home/nv/haarcascade_frontalface_alt.xml")
    rects = cascade.detectMultiScale(img, 1.3, 4,
cv2.cv.CV_HAAR_SCALE_IMAGE, (20,20))

    if len(rects) == 0:
        return [], img
    rects[:, 2:] += rects[:, :2]
    return rects, img

def box(rects, img):
    for x1, y1, x2, y2 in rects:
        cv2.rectangle(img, (x1, y1), (x2, y2), (127, 255, 0), 2)
    #cv2.imwrite('/home/nv/m.JPG', img);

rects, img = detect("/home/nv/img.JPG")
box(rects, img)
cv2.imshow('img',img)
cv2.waitKey(0)
cv2.destroyAllWindows()
#crop_img=image(rects, img)
#cropped.save('L_2d_cropped.jpg')
