it should still fix some issue I think you're looking for array auto-unpacking as described here: How to iterate over an array of arrays
d = (from..to).map {|d| [ d.year, d.month ] }.uniq

d.each do |year, month|
  # For Year
  puts year

  #For Month Number
  puts month
end

#   ^ Rows  ^ Cols  ^ Channel
# The colon alone indicates no slicing, so here we select
# all rows, and then all columns, and then 0 indicates we
# want the first channel from the CMYK channels.

How to convert a string to array and convert each of the hex value in array to decimal in python?

wish of those help If you're using Python 3.5+ you can use the bytes.fromhex method to convert hex string to bytes, and use the list constructor to convert bytes into a list of integers:
>>> list(bytes.fromhex('7f33117cf266a525'))
[127, 51, 17, 124, 242, 102, 165, 37]
>>> bytes([127, 51, 17, 124, 242, 102, 165, 37]).hex()
'7f33117cf266a525'

wish help you to fix your issue You can do it in two ways:
You can use opencv for this. To converts the image from Gray to RGB:
import cv2
import numpy as np
gray = np.random.rand(256, 256)
gary2rgb = cv2.cvtColor(gray,cv2.COLOR_GRAY2RGB)
import numpy as np
def convert_gray2rgb(image):
    width, height = image.shape
    out = np.empty((width, height, 3), dtype=np.uint8)
    out[:, :, 0] = image
    out[:, :, 1] = image
    out[:, :, 2] = image
    return out

gray = np.random.rand(256, 256)  # gray scale image
gray2rgb = convert_gray2rgb(gray)
