[Python] I'm having problems recognizing text from a picture, python

I was given a school project for recognizing various kinds of CAPTCHA, and I had some difficulties with its implementation.

Images of this type will be fed into input ,,.

I handle them with the following code:

import cv2
import pytesseract

# load image
fname = 'picture.png'
im = cv2.imread(fname,cv2.COLOR_RGB2GRAY)

pytesseract.pytesseract.tesseract_cmd = r'C:\Tesseract-OCR\tesseract.exe'

im = im[0:90, 35:150]

im = cv2.blur(im,(3,3))

im = cv2.threshold(im, 223 , 250, cv2.THRESH_BINARY)
im = im[1]

cv2.imshow('',im)
cv2.waitKey(0)


After all processing, the image looks like this: And at this point, I have a problem, how can I modify the image to good readability by the computer, so that instead of the wrong TAREQ. he would display the 7TXB6Q

I am trying to display text from an image with the pytesseract library as follows

data = pytesseract.image_to_string(im, lang='eng', config='--psm 6 --oem 3 -c tessedit_char_whitelist= ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789')
print(data)


I am writing here hoping to get valuable advice (perhaps you know the most suitable way to get text from a picture or process the image pinned above). )
