Creating functions to read the image files

As mentioned earlier, it is not possible to directly view the images in your downloaded image files. So, we will now create a function in Python that the matplotlib module will be able to use to display the images in the files:

def loadImageFile(fileimage):  f = open(fileimage, "rb")  f.read(16)  pixels = 28*28  images_arr = []      while True:    try:      img = []      for j in range(pixels):        pix = ord(f.read(1))        img.append(pix / 255)      images_arr.append(img)    except:      break  f.close()  image_sets = np.array(images_arr)  return image_sets

The preceding loadImageFile function takes a single parameter, which is the name of the file that contains the images. We have two such files available for us in our downloaded files folder: ...
