How to give a piece of code to the Yandex bot, but not give it to others?

Question

Python

Please help me solve a small problem. There is this code in the header of the site:

<?php if (is_page_template( 'brokers-cards-template-noajax.php' )  ) : ?>
 <meta name="fragment" content="!">
<?php endif; ?>

You need to give a piece of code only to the Yandex crawler, but close it for the rest. Tell me how to do it, maybe wrap it in some other condition? I practically do not understand PHP, so if you can just throw off the finished piece of code. Thanks <meta name="fragment" content="!">

Answer 1

For data preparation, sklearn is a great choice. The library contains a number of preprocessing tools . Some more examples can be seen here .

Answer 2

anyway, Yandex bot does not always send the required user-agent header values)
