OCR Python get wrong characters

I am trying to recognize text from this image

enter image description here

here is my trial

import cv2
import numpy as np
import pytesseract
from PIL import Image

# Path of working folder on Disk
src_path = "E:/PythonApps/characterRecognitionWithTuneWithVoice/"

def get_string(img_path):
# Read image with opencv
img = cv2.imread(img_path)

# Convert to gray
img = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)

# Apply dilation and erosion to remove some noise
kernel = np.ones((1, 1), np.uint8)
img = cv2.dilate(img, kernel, iterations=1)
img = cv2.erode(img, kernel, iterations=1)

# Write image after removed noise
cv2.imwrite(src_path + "removed_noise.png", img)

#  Apply threshold to get image with only black and white
#img = cv2.adaptiveThreshold(img, 255, cv2.ADAPTIVE_THRESH_GAUSSIAN_C, cv2.THRESH_BINARY, 31, 2)

# Write the image after apply opencv to do some ...
cv2.imwrite(src_path + "thres.png", img)

# Recognize text with tesseract for python
result = pytesseract.image_to_string(Image.open(src_path + "thres.png"), lang='eng')

# Remove template file
#os.remove(temp)

return result


print '--- Start recognize text from image ---'
print get_string(src_path + "Untitled.png")

print "------ Done -------"

but i got wrong text characters as below

Might be there is something wrong with your eng tessdata, which tesseract OCR version and eng tessdata you are using?

Try replacing this eng tessdata in tessdata directory

p.s. your code and image give exact output you desire with the configuration: eng tessdata and tesseract version 4.x in my machine.
