How to remove the p from the default wordpress editor?

I would like to remove this letter p too.
It appears in Visual mode, not Text mode.

Same question i have asked in the stack overflow i got one reply from there,
One solution is

/** Edit TinyMCE **/
function myformatTinyMCE($in) {
    $in['statusbar'] = false;

    return $in;
}
add_filter('tiny_mce_before_init', 'myformatTinyMCE' );

Second Solution is

function my_theme_add_editor_styles(){
    ?>
        <style type="text/css">
            .mce-path   {display: none!important;}
        </style>
    <?php
}
add_action( 'init', 'my_theme_add_editor_styles' );

it is a css option.

Thanks, the second solution works, although I had to tweak the css:

function my_theme_add_editor_styles(){
    ?>
        <style type="text/css">
            .mce-path-item.mce-last {
                display: none !important;
            }
        </style>
    <?php
}
add_action( 'init', 'my_theme_add_editor_styles' );

A 3rd solution is to add a custom css file to your theme css folder, named my-admin-style.css:

/* removes letter p below text area in tinymce editor */
.mce-path-item.mce-last {
    display: none !important;
}

Then add this function, load_custom_wp_admin_style(), to your theme functions.php file:

function load_custom_wp_admin_style() {
        wp_register_style( 'custom_wp_admin_css',
        get_template_directory_uri() . '/css/my-admin-style.css', false, '1.0.0' );
        wp_enqueue_style( 'custom_wp_admin_css' );
}
add_action( 'admin_enqueue_scripts', 'load_custom_wp_admin_style' );

Why would you want to do this?

A css file is where you expect to find css styles, rather than looking in a php file. It makes it convenient to add future admin css changes.

Also, I did not like where solution two placed the style in the admin HTML web page – above the head tag, although it seemed to work ok.

No, what I meant was, why do you want to remove the p?

The letter p is not useful, and just clutters up the page.
Since it is a single character with no label, it appears to the user as an extraneous character. In earlier versions of Worpress it had a label, Path, but even then it was completely worthless.
