how to print what is there is in a variable to the frame.

edit

Check argument type : this program is good

img = np.zeros((256,256,3),np.uint8)
 x = cv.putText(img,'test',(100,10), cv.FONT_HERSHEY_SIMPLEX, 1.0,(255,255,255),lineType=cv.LINE_AA)

but this is wrong :

x = cv.putText(img,['test'],(100,10), cv.FONT_HERSHEY_SIMPLEX, 1.0,(255,255,255),lineType=cv.LINE_AA)
 File "<stdin>", line 1, in <module>
TypeError: bad argument type for built-in operation

or this one

 x = cv.putText(img,49,(100,10), cv.FONT_HERSHEY_SIMPLEX, 1.0,(255,255,255),lineType=cv.LINE_AA)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad argument type for built-in operation

What's server url locators ..... response = url? Try this:

import cv2 as cv
import numpy as np

img = np.zeros((256,256,3),np.uint8)
response= 'opencv.org'

cv.putText(img, response,(0, 50),
               cv.FONT_HERSHEY_SIMPLEX,
               3,(0, 0, 255),
               lineType=cv.LINE_AA)

cv.imshow('frame', img)
cv.waitKey(0)
