and the code is ...:
path = "F:/New folder"
hand_picturs = []
for i in range(6):
hands_pic = cv2.cvtColor(cv2.imread(path + str(i) + ".jpg"), cv2.COLOR_BGR2RGB)
hand_picturs.append(hands_pic)
your image was never read correctly. you have to check for None or such after imread() EACH TIME YOU USE IT. don't blindly chain calls, which could fail.
print out, what you use for a filename, it's broken (missing seperator).
