Translate Hindi language to English using Python
<p>I'm doing a project on recognizing language(English, Hindi, Marathi, etc..) depends on origin language code and translate it into another language depends on input targeted language code.</p>

<p>Everything is done in Python language.</p>

<p>Google API to recognize language and interpret in text format then using Microsoft API translate it into another language.</p>

<p>But I'm facing an error, here it is</p>

<pre><code>Traceback(most recent call last):
