title: How to merge f string with b string in one line usage in Python
body: <p>I can create <strong>b-sting</strong> this way:<br>
  <code>name_binary = b'Adam'</code><br>
  but if I have variable like <code>name='Adam'</code> and I want to make at once usage of <strong>f-string</strong> and <strong>b-string</strong>:<br>
  <code>name_binary = fb'{name}'</code><br>
  I get:</p>
  
  <pre><code>   File "&lt;input&gt;", line 1
      c = fb'{a}'
                ^
  SyntaxError: invalid syntax
  </code></pre>
  
  <p>I know that I can do:<br>
  <code>name_binary = name.encode('utf-8')</code></p>
  
  <p>But technicality is that possible by using <strong>b</strong> and <strong>f</strong> together as on my example?</p>
