I have troubling with images display, they didn't show, it show empty list

[Rock8090]

import glob

import cv2 as cv
path = glob.glob('C:/Users/DELL/Desktop/Documents/Ritesh Sir/Pulses_Images/*.jpg')

cv_img = []
for img in path:
n = cv.imread(img)
cv_img.append(n)
cv.imshow(cv_img)
cv2.waitKey(0)
cv2.destroyAllWindows()
cv_img

[datasciencecompleteguide]

1. for img in glob.glob(r'C:/Users/DELL/Desktop/Documents/Ritesh Sir/Pulses_Images/*.jpg'):
2. replace cv2 with cv
3. Check the extension of the images stored in the Pulses_images folder. (Are they jpeg or jpg or some diff. extension)

import matplotlib.pyplot as plt
import matplotlib.image as mpimg
import glob

import cv2 as cv
path = glob.glob('C:/Users/DELL/Desktop/Documents/Ritesh Sir/Pulses_Images/*.jpg')

cv_img = []
for img in path:
n = cv.imread(img)
cv_img.append(n)
cv.imshow(cv_img)
cv.waitKey(0)
cv.destroyAllWindows()

still i'm unble to visualize the images
