title: What does = (equal) do in f-strings inside the expression curly brackets?
body: <p>The usage of {} in Python f-strings is well known to execute pieces of code and give the result in <code>string</code> format (some tutorials <em>here</em>). However, what does the '<strong>=</strong>' at the end of the expression mean?</p>
  
  <pre><code>log_file = open("log_aug_19.txt", "w") 
  console_error = '...stuff...'           # the real code generates it with regex
  log_file.write(f'{console_error=}')
  </code></pre>
