Install Python. Then install the following two libraries using the Command Prompt (cmd) interpreter in Windows10:

Python will automatically translate the following html tags with the googletrans library:

py -m pip install "googletrans"
py -m pip install googletrans==4.0.0rc1
py -m pip install beautifulsoup4

Also, Python code will also automatically translate the contents of the following tags (Your Text), but only if these tags are framed by < ! -- ARTICOL START --> and < ! -- ARTICOL START --> html comments. Of course, you will need to replace these tags with your own tags.

<!-- ARTICOL START -->

<h1 class="den_articol" itemprop="name">Your Text</h1>
<p class="text_obisnuit">Your Text</p>
<p class="text_obisnuit2">Your Text</p>
<span class="text_obisnuit2">Your Text</span>
<span class="text_obisnuit">Your Text</span>
<li class="text_obisnuit">Your Text</li>
<a class="linkMare" href="https://neculaifantanaru.com/en/">Your Text</a>
<h4 class="text_obisnuit2>Your Text</h4>
<h3 class="text_obisnuit2>Your Text</h3>
<h5 class="text_obisnuit2>Your Text</h5>

<!-- ARTICOL FINAL -->
              

THE CODE: Copy and run the code below in any interpreter program (I use pyScripter) . Don't forget to change the path in the "files_from_folder" line. And here is the list of languages that can be translated: LANG.

from bs4 import BeautifulSoup
from bs4.formatter import HTMLFormatter
from googletrans import Translator

translator = Translator()

class UnsortedAttributes(HTMLFormatter):

                try:
                    node.contents[x].replaceWith(translator.translate(node.contents[x], dest=destination_language).text)
                except:
                    pass
        elif node.contents[x] != None:
            recursively_translate(node.contents[x])

That's all folks.


If you like my code, then make me a favor: translate your website into Romanian, "ro".

Also, there is a VERSION 2 of this code or VERSION 3 or VERSION 4 or VERSION 5 or VERSION 6

I wrote this book that conjoins in a simple way personal development with leadership, just like a puzzle, where you have to match all the given pieces in order to recompose the general image.
